Logitech MX518 Gaming Optical Mouse - Metal Reviews

• Superior Gaming mouse and excellent mouse overall

  
  By ACISLJANCZZ6L on 2005-05-06
  I like this mouse a lot. With the right mouse pad (a Microthin Wow!Pad from Office Depot), this mouse glides beautifully, never seen one better. The main buttons are easy to push (only Microsoft does this right also). The forward and back side buttons are a little small but work fine. The scroll wheel is not as nice as the MS Intellimouse 4 as it still clicks and is harder to roll. Never used the tilt wheel on the MS mouse. It is gaming where this mouse shines. The mouse tracks no matter how fast I move the mouse. The mouse never sleeps so it always responds perfectly. Frankly, I have not yet found any use that I needed to change the mouse resolution (i.e. speed) but in trials that is easy to do.
  Feel is good, middle to small sized so fits most of my family. Cord is thin and a little stiff so it does not always lay completely flat (I have not found on that did). Very lightweight. Contoured nicely to fit the cupped hand.
  Worked with Win XP as soon as I plugged it in, drivers and program loaded with no hassle.
  Nice job, Logitech!
  
  

• Great Mouse, But Beware Of USB Port Issues

  
  By A3EZ2PLA8AFPIF on 2006-01-30
  I did a lot of research before I finally decided to purchase the Logitech Mx518. I decided against wireless and this Logitech product got some of the best reviews out there. So I decided to get it. As soon as I hooked it up to my usb port I was amazed at the sensitivity and control. However, once my computer went into the screen saver mode, the mouse just went dead. It would not work again until I unplugged it, and plugged it back in to my usb port. I downloaded the newest software from Logitech, no good. It still locked up after the screensaver kicked in. Logitech tech support never returned my emails. So, I went to a local retailer where the "geek" (hint, hint) there told me my situation was a common problem with the Mx518. I was advised to connect the mouse directly to the mouse port in the back of my computer ( PS/2 not the usb) and see what happened. So, I hooked up the mouse to the "old fashion", PS/2 mouse port in the back of my computer tower and it has been fine ever since (about 2 weeks now). After the initial "troubleshooting" I am very please with this mouse. However, I doubt I would purchase this same model again due to its issues with the usb ports. ****August 2007 Update: the thumb browser "back" button has stopped working. So far 1 week and several efforts, but no reply from Logitech Warranty/Support****
  
  

• As Good As a G5 And Cheaper Too

  
  By A2IZPQY17M81CZ on 2007-04-11
  Those of you who have read my G5 review might be surprised that I bought an MX518 instead of a G5. I'm pretty high on the G5, and rather sad about breaking it, but I was curious about the MX518, if for no other reason than it is the standard by which the G5 is so often compared.
  
  I've been using the new mouse for about a week and it's hard to distinguish performance-wise from a G5. But there are some differences worth mentioning.
  
  What I Miss About the G5 -
  
  Separate X and Y axis sensitivity settings - this feature was only available in SetPoint's Game Mode but did give me some flexibility in opening up the horizontal sensitivity for close-in sweeping without sacrificing vertical precision.
  
  Adjustable weights - My G5 as described in my review weighs 140g; the MX518 weighs 105g. The weight module on the G5 makes the entire difference. I've noticed the difference, but have adjusted without too much trouble.
  
  Sensitivity Indicator - Occasionally I'd lose track of the mouse sensitivity and had to look at the G5's LED indicator, which in some cases was easier than wiggling the mouse.
  
  What I Like Better About the MX518 -
  
  Two thumb buttons which I've set for raising and lowering sensitivity a la user.xml customization similar to what I did on my G5. Their location is still a bit high.
  
  BTW, the SetPoint software will detect the MX518 and append user.xml with default settings for the MX518. This is cool as it allows one to switch back (or use in parallel) to a G5 without losing any customization.
  
  Toss-Ups -
  
  The size and shape of the MX518 and G5 are identical, however my G5 had a slightly rougher texture both on its' topside and its' gripping surfaces. The MX518 is more slippery in both areas, so those who tend to rely on palm friction for grip might prefer a G5. I tend to use my thumb and pinky to hold the mouse, so it's not as noticeable.
  
  Conclusion -
  
  The G5 was the best mouse I ever owned, but the MX518 is an acceptable and more cost-effective replacement.
  
  Public Service Announcement - How to "Deep Hack" your MX518 --
  
  The SetPoint utility keeps its' configuration info in a file called user.xml (I forget the path, but it's stored in the Documents and Settings directory on XP). Editing the file itself is not difficult - because it's XML, any text editor will do. It's WHEN one edits that's important. SetPoint guards against accidental changes or deletions by rebuilding the user.xml file when it exits. So you have to do the following:
  
  1) Close SetPoint, either from the system tray or going into the task manager.
  2) Copy user.xml to user.xml.orig or whatever suffix you use to save an archival copy.
  3) Edit user.xml, by copying and pasting the tags for the normal "increase sensitivity" button to button 4. For the MX518, I also copy and paste the normal "decrease sensitivity" button tags to button 5. If like me you want to use it for games that you've set up for SetPoint's "game mode", you'll also have to change the section in user.xml dealing with game mode. Otherwise, the change will fail as soon as you run the game.
  4) Delete last_user.xml.
  5) Open SetPoint. In my case, I logged out of XP then logged back in to reload SetPoint.
  
  The end result is that outside of game mode, both the standard increase / decrease sensitivity buttons and the thumb buttons can change the mouse sensitivity. In game mode, only the thumb buttons can change the mouse sensitivity. This is because game mode has a different XML syntax than default mode. Conceivably this technique can be used to arbitrarily reprogram all of the buttons. Make sure you backup user.xml before charging in!
  
  
  

• Freaking Wonderful!!!!

  
  By A166R0QB2CM9UK on 2005-04-23
  This mouse is the greatest mouse to have come out! The mx510™ is also a wonderful mouse, but this is the icing on the cake. How does it compair to the Razor™ Diamondback™ you ask? Well to sum it up for yall it blows it out of the water! Alright might have been a little short so here it goes. The mx518™ has many new features, it has new software, 1600 dpi that can be lowerd to any dpi setting you want with a click of a button. For all you n00bers out there(newbies) higher dpi enables faster movments over a higher resolution which is good for using aps, but for me i rather play with a smaller dpi for gaming because it allows more precise moving with lower sensitivity. Plus it has the 5.8 megapixle optical lens which is the highest out right now. I hope this was helpful and logitech™ all the way!
  
  

• Not for lefties

  
  By AZDPODK6VBV1M on 2006-02-25
  At my sorrow, I bought this mouse for gaming, coz it supposed to be good for that. Since Im leftie, I am using a left hand to operate a mouse. And I can tell u that this mouse is impossible to use with a left hand. Crap! And it wasnt written in any review, or at any place on the box for this one, so I just spent 50$ for nothing.
  Lefties, lets get some petition please, to make these manufacturers working the left versions of those mouses.
  Untill than, only 1 star.
  
  
• Can't Take the Pressure
  By A1RDFY8AI66DY8 on 2006-06-06
  I burned through 2 of these MX518's, the first one I bought and the replacement the company sent. It took about three months apiece. They work great to start but if you have anything but a soft touch they can't take it. And I don't mean abuse-Just serious use. If you advertise yourself as a GAMING mouse...HELLO-you'd better be able to handle serious gaming. I'm not even going to go through the hassle of trying to get ANOTHER replacement. If I had it to do all over again I'd start with another brand!
  
  
• BEWARE: MX518 is not Mac compatible!!!
  By A1GALI61Q3OPZ5 on 2005-05-05
  As a proud owner of the MX510 (which I love), I wanted to have the latest and greatest edition! I assumed that the MX518 would be Macintosh compatible, but alas it is not and I was sorely disappointed when I bought one! This is the first time I have heard of a Logitech mouse not working with the Mac. Message to Logitech: PLEASE FIX THIS so that Mac users like me can use the MX518! At the very least, PLEASE MARK THE BOX VERY CLEARLY THAT THIS IS NOT MACINTOSH COMPATIBLE.
  
  
• Excellent mouse, buttons not very durable
  By A2WLHCCA0FXCJX on 2005-12-23
  After 6 months my MX518 developed a problem with the left button. The button still works, but there is a werid creaking/scraping tactile feeling when you press it. I believe this is due to internal plastic parts deforming with time. All this mouse was used for was light browsing. I loved the mouse, but this is the second Logitech mouse with button problems (G5 is the other). I will research Microsoft's offerings before buying another MX518.
  
  
• KICK ASS
  By A22SKD6EKCLC38 on 2006-03-25
  I do alot of graphic design and 1st person shooter games. I have used several mouse's from the razor boomslang to the G5 and all of them went to ebay. This MX518 is top notch super high dpi for quick reaction and on the fly dpi dropping for sniping or pixel to pixel movement. If this mouse dont make you extremely satisfied then nothing will.

• Great Mouse, but Beware the Software
  By A6M09JGSBX7LQ on 2006-08-18
  The MX518 is a great mouse, and I've noticed a marked improvement in movement and precision in both games and graphics work. There are two things to be wary of, though.
  
  First, the Logitech SetPoint software that is included can cause serious problems with other programs. In my case, it will occasionally freeze the entire computer while using FireFox in Windows XP, forcing a manual power-off reset. Even after uninstalling the SetPoint software, the problem still persists, though it is less frequent. Fortunately, most of the features, including the default 3-level DPI switching, work without the SetPoint software.
  
  Second, the application/document-switch button is located in a very awkward position and is prone to accidental triggering during normal use of the mouse. This is especially problematic when playing an FPS game and suddenly finding yourself staring at a Windows desktop. The good news is that if you don't install the SetPoint software, this button is ignored by the system.
  
  Overall this is a good product that delivers as promised, but the software issues prevent it getting a 5-star rating from me.
  
  
• Pro-level gaming mouse
  By ATX2D6KCMQ72N on 2005-12-01
  Excellent mouse. It's only slightly better than the 510, so if you already own that mouse, i don't recommend it. The sensitivity adjustment button is not useful for counter-strike, but i hear its quite useful for BF2.
  If you are going to buy this pro-grade mouse for gaming, i would highly recommend purchasing a quality mousepad along with it. The mouse-feet on the pad is very good and it glides like ice along most surfaces, but nice mousepads, in my opinion make a bigger difference than the mouse itself. I would recommend a steelpad QcK, it's very cheap and made of cloth, yet is durable. It has just the right amount of friction. If you don't like cloth-type mousepads, there are so many other good ones, such as Icemat, or another steelpad.
  
  
• Great mouse for 5 months
  By A2C86D4SJLW5VN on 2006-01-03
  Having had two mx510 mice expiring on me within a year, I chose to purchase an mx518. When it works, it's a great mouse but suffers from the same problem as every other logitech mouse, weak mouse contacts. This has been marketed as a pro gaming mouse and yet the durability is shockingly poor. For £40.00 I expect more and the whole problem can be cured by upgrading the contact which is manufactured by Micron Industries. Logitech obviously don't see this as a problem despite the fact that this issue looms large in gaming forums. Logitech have lost me as a customer so will be buying a Razor Copperhead with my refund!
  
  
• Nice product
  By ADKOIV0YNBM8G on 2006-03-17
  I had been using the MS Intellimouse Explorer 4.0 for a couple years or so with no problems, however over the last couple months I'd noticed some difficulty in basic clicking of links, icons, etc. Thinking that perhaps the button had just deteriorated, I began the search for a corded mouse.
  
  While I do play some games (Civ4, other strategy) I am not a "hardcore" gamer. A much higher percentage of my time is spend on standard desktop computing tasks (surfing, paying bills, writing documents, etc.). That being said, I still wanted a reliable mouse with good ergonomics. I decided to go back to Logitech (I'd had a wireless trackball mouse a few years ago and loved it until it just went DOA one day).
  
  After looking at the full Logitech lineup, I decided on the MX518 based on ergonomics (similar to Intellimouse), technology (optical), and price (mid-range).
  
  Got it home, and it pretty much works as advertised. Clicking is very precise, accurate, crisp. Buttons are fairly easy to reach. Feels solid. I'm not that wild about the "metal" look; I prefer something a little more standard. At the same time though I realize that I, being 38, am probably not the demographic that Logitech is shooting for with a "gaming mouse"!
  
  Anyway, bottom-line it's a very solid mouse that I think will do anything and more that someone would want to do on a computer, whether it's games or otherwise. I personally could never justify spending $80 on some of the other mouses on the market; you'll just never convince me that they'll do that much more than what this mouse will do.
  
  As it turns out, I'm actually going to return the MX518 today as I think $50 is a lot to pay for a mouse, and because I found out the Logitech is actually releasing a brand new MX400 Laser mouse in April that will retail at $39, does not have the "metal" look, and is designed for desktop users like me. I'm going to hold out for this one as I just think it's a better fit for my personal needs. However, the MX518 is a very solid mouse and I would recommend it (although since I haven't used it for gaming I really can't tell you how much better it is than any other optical mouse from Logitech). But my instinct says, not much!
  
  
• Macintosh Compatibility with Steermouse
  By A2VYO89DB7HWZM on 2006-06-17
  I've used the MX500 for years but needed a new mouse and Logitech don't sell that one anymore. I got the MX518 but there are no Mac drivers for it from Logitech. After trying USBOverdrive which didn't work I found Steermouse which does.
  
  Supports all the buttons in a wide variety of options. And has the Holy Grail that the Logitech drivers didn't have; the ability to have different button sets for different applications.
  
  The MX518 is lighter than the earlier MX mice I've had which is good for feel but we'll see how it lasts. But for now I love it.
  
  
• MX 518 FOR GAMING!?
  By AKWMA4F66T07T on 2005-12-16
  Logitec's mice absolutely blow for longevity. The scroll button is toast again after 5 months of gaming. I have been through 3 logitech mice in 1 1/2 years. There is no way to repair them since they are made as disposable. Guess Logitec mouse producers either don.t game or dont care. Im goin razor next, just not looking forward to having get used to a different feel mouse. As for 1600 DPI, what a waste of cash. Ive never found a use yet in all my gaming for anything more than 800 DPI.
  
  
• Very Good Mouse
  By A1V7QEEB9KCE4J on 2006-08-14
  I have been using computers since the late 1960s, and have been using mice since the early 1980s. I have used more of these devices than I can count. But this is the best one I have every used. Weight, hand fit, smoothness of movement, and so on. This is the second MX518 I have owned. I bought my first over a year ago. I use a computer all day long and typically replace my keyboard and mouse about every six months, due to wearing them out. But the MX518 lasted for over a year. Its failure mode seemed to be cord fatigue. And as you can see I was so pleased I bought the same mouse a second time.
  
  
• MX510 for Mac OSX? No more...what about the MX518 for Mac OS X?
  By A37UZ9ZNJASBV9 on 2006-11-24
  Well, I wanted to get the MX510 because the Logitech Control Center worked with it. Well, good luck finding a MX510. So, I got the MX518. Well, guess what? Logitech Control Center does NOT work with the MX518 for Mac OS X.
  
  What to do? I did some research and find out that if I downloaded a helper app called, "USB Overdrive (shareware) it would work with the MX518 for Mac OS X." So, far so good. Do a search for "USB Overdrive" and see if it satisfies your needs. All I wanted was a control app that allowed me to program each of the eight buttons (wheel included) on the MX518. Well, you can with USB Overdrive (Mac OS X). And yes, the 1600 dpi is great! A lot better than the MX510's 800 dpi.
  
  If you don't want to mess with USB Overdrive, I recommend getting the Razer Pro| Click v1.6 for the Mac OS X. http://www.razerpro.com/
  
  They have native Intel/PPC drivers for Mac OS X. So, no shareware needed. And yes, they sell the Razer Pro | Click v1.6 on http://www.amazon.com :)
  
  P.S. I've also heard that the Razer Diamondback mouse also works with the Razer Pro | Click software. Anyways, I give the MX518 only four stars (****) because I wanted Logitech to release drivers for this mouse on Mac OS X. I'd give it five stars if they did that!
  
  
• "It rocks"
  By A3LUH8V2LX15H7 on 2005-08-03
  I recently built a gaming computer for my 16 y/o son. He likes playing first person shooters and action games and he is currently really into "Battlefield 2" on line. He is a boy of few words, and not much impresses him, but he is a really good kid. When i gave him the MX518 several weeks after he started using his new computer he said it helped his game play, especally being able to adjust the mouse settings. He also liked the way it felt and looked. For him "it rocks" is a ringing endorsement.
  
  
• Forget all those *OTHER* mice, and GET THIS ONE!
  By A25YIQJGY9DVEU on 2005-08-15
  I have been gaming for all of my life, and after getting this mouse I decided that having never reviewed any other product, I should review this one. I did my research before I got this mouse, and noticed only one review here, so hopefully this will help some of you out.
  
  This mouse is amazing, comfortable (even for large hands), fast, precise, and worth every cent I paid for it. I got it for a shade under $40, at Amazon.com, it was the cheapest place I could find it. MSRP = $50
  
  
  DPI = 1600
  
  
  This matters in games because the higher the DPI, the faster the mouse will move with less effort. In contrast, the lower the DPI, the slower the cursor will move with more effort. In effect, high DPI for navigation in fast games like UT 2k4 and CS. Low DPI for sniping. Awesome!
  
  
  15 g of acceleration (480 ft/s squared)
  
  
  I own a Microsoft Wireless Suite (Optical Mouse 2.0) and there is obviously lag whenever I move the mosue too quickly, not so good for gaming. I did a little math after looking at the specs on this mouse, and you would have to move the mouse faster than 327 mph for it not to be able to track your movement (assuming that's not impossible and you have a big enough mouse pad!) This mouse is really ergonomic and I think it's important to note that your thumb is supported completely off of the mouse pad. For those serious gamers: there are those of you who like the thumb on the mousepad for precision control (I suggest teh Razor for that) and then there are the majority who don't like the thumb on the mousepad. Get this mouse, your pinky and thumb will not be touching the mousepad. This mouse is very light and slick and easily glides on the mousepad. However, I recommend a plastic-type mousepad over the cloth for maximum precision. Mostly because it glides easier on this surface than any other.
  
  
  The only beef I got is: it's pricey for a mouse! But it's worth it!
  
  
  
  
• Logitech MX518 Gaming Optical Mouse
  By A2W1UUXBT4T1WS on 2006-03-22
  Wow! What a difference a gaming mouse makes in FPS games. I love the additional buttons and the ability to change sensitivities on the mouse. Love it.
  
  
• Perfect Gaming Mouse
  By A1GP1IGQ33BL42 on 2006-11-30
  Whether it is World of Warcraft or Battlefield 2, this mouse glides perfectly to its destination. I've been an Gamer for some time now, and can categorically say that I have not ever encountered a better mouse. The pixel adjustment is precise, allowing you to aim quickly and accurately whereas the alternate keys on the side make throwin grenades or using secondary fire a breeze. Finally, there is a button on the actual mouse that allows you to switch between screens so if you aren't a gamer, you can easily swap projects on your desktop. Past all of this, the design is extremely comfortable, allowing your thumb to lock into the mouse in a way, and providing better control. The right and left mouse buttons click easily and accurately as well.
  
  Whether you're a gamer or a graphic designer, this mouse is the mouse for you. Haven't found a use yet that this mouse hasn't made quicker/easier.
  
  
• Perfect for both PC Gamers and websurfers
  By A10FGXGHS2VS9 on 2006-12-20
  I bought this mouse in April of 2005 and I haven't had a problem with it. Perfectly tracks on all surfaces I have tested (though I'm sure highly reflective ones might cause a bit of problem). Honestly, I haven't found the DPI switching to be a feature I use very often, but it doesn't hurt.
  
  Buttons have a very nice tactile feel. Especially useful are the two buttons on the left side of the mouse which default to paging forward and back in your webpages. After spending any significant time with this mouse, it's hard to surf the web with any other mouse; you'll constantly be pressing the nonexistant side buttons in an effort to navigate. The forward and back action also works when browsing through files and folders, which is also very helpful.
  
  Finally, ergonomics on this mouse are absolutely incredible, at least if you are right handed.
  
  Do not hesitate to buy this mouse
  
  
• Two in one Eye Surgery / Gaming Device
  By A1YUQ8QJ5209TB on 2005-09-19
  I must say this is a pretty good mouse. High sensitivity, unprecedented control levels and 1600-dpi ultra high resolution make this a no brainer for the ultimate gaming experience. However, I also found that staring directly into its optical red light for a couple hours is great for removing cataracts. Awesome product.
  
  
• Solid
  By A27IWRPD3PNTZB on 2006-01-10
  I've used this mouse for 3 months so far after my Microsoft mouse died on me. It has been great, the clicks are perfect and the overall feeling is very good. There are no cons to this mouse and thats why I love it.
  
  
• A Real Gaming Mouse
  By A22L47C6L0TC1R on 2006-02-23
  This is a great gaming mouse. If customizable wieght and even higher dpi is really necessary, then go for the g5. I used the g5 for a few weeks and decided 2000 dpi was too much since I wasn't even using it at that at that high sensetivity, I also found the wieght system annoying becuase I kept thinking that I might need to change the wieght when ever I died. The mx518 was exactly what I needed. I love this but rarely use the on the fly sensitivity change feature while playing games, more for picture editing. My favorite feature is the left and right clicker on the side of the mouse which is fully customizable. I uses it in firefox to switch tabs in a second with ctrl+pgup and ctrl+pgdn! then I binded the window switcher to close the tab too (ctrl+w). Surfing the web is 10 times faster now. The g5 did allow you to have multiple programs know different commands without changing it on the mouse, sadly I wasn't able to do this on the mx518 :(. But when I really need to change it, it just takes a second. Also, you don't have to install any software to still be able to use the auto sensitivity switcher, but not any other shortcuts on the mouse, if you need to free up processes running the in background. Overall, it's an excellent mouse worth the price.
  
  
• Pleasant
  By A2A0GW1OXO7YDL on 2006-03-17
  I've used the mouse for 3 month now. It replaced a Logitech Optical that broke. This is a desktop mouse, aimed for comfort and precision, rather than compactness of its laptop counterparts.
  
  The mouse itself is pretty light and quite responsive to control. More importantly, the buttons do not stick and response is tight, particularly for first person shooters.
  
  The software I installed from the manufacturer had an option called "mouse pointer acceleration". This basically gave your movements 'inertia' so that the mouse pointer continued to move in a direction even after you have stopped moving the mouse. It seems to be a useless feature and was counter to my previous experience with mouse.
  
  Other than the above, the mouse is very nice. It comes with a wide assortment of buttons and fit should fit the contour of most hands.
  
  
• Great Mouse for a Graphic Designer!!!
  By A38ZRCBPRQ0SWC on 2006-07-19
  I've had it for a few days and i love it already. It works perfectly fine. It's accurate. And i dont use it for games, just for designing...and it's really good for that. I recommend it!!! =)
  
  
• Finally a mouse without annoyances
  By A3A8FSGB8OZWY3 on 2006-10-05
  I've gone through about 6 different mice, and each one had their pros and cons (mostly cons). I finally found the MX518, and trust me, you don't know what you're missing until you've used it. *Edit: how did I find it? On SK-Gaming, there are tons of threads about "what's the best mouse"? This mouse came up so frequently that it seemed like a no-brainer.
  
  This is the first time I can use a mouse and never have to worry about unexpected friction or hiccups. It controls with extreme precision and ease. At first, it was a little hard for me to get used to the shape and size, since it feels different from other mice I've used...but once I got used to it, it's flawless.
  
  I am also a pretty avid gamer, and since I got this mouse, my performance has gone up noticeably. In fact, that's the reason I got this mouse to begin with: my biggest weakness in-play was my inability to consistently click quickly on small units in battle. With the MX518, those kinds of dumb problems go away.
  
  Another thing I love is that even if I used it for hours, my hand feels completely rested and fresh. No more taking quick hand breaks, stretching it out or what not.
  
  It's also very easy to customize the speed and feel of the mouse using the software. I've read some complaints about it, but I can't see any way to improve it.
  
  Coupled with my Steelpad S&S mousepad, it's so much more fun to get on the computer. Like upgrading car audio, you really don't know what you're missing until you get rid of your outdated junk and try the best.
  
  
• good gaming mouse
  By A195LZOIVNSJYX on 2006-11-09
  I was using a MX510 prior to getting this. There is a slight upgrade in performance from the 510. The ability to adjust the sensitivity on the fly wasn't that useful. It was hard to adjust to the different levels and it would change the sens setting in game. So, I set the mouse software to the highest level and adjusted the in game settings to where it felt good. The biggest difference I felt is it's easier to make longer range shots, I'm sure because of the higher resolution of the 518 over the 510.
  
  
• Doesn't work as advertised
  By A2R3SUSBX369NS on 2007-02-23
  I have used an application switch funtion on my mice ever since 1998, so I'm a bit of an expert when it comes to this feature. It is why I bought this mouse. However, the application switch on this mouse only works occasionally. No, it's not a hardware deficiency, the software is just buggy. Logitech threw this together, and they aren't diligent about updating the driver to make sure it works well all the time. I see this a lot from software companies, once they make the sale, all the smart people within the company move on to new projects, and the product they sold in the past gets left in the dirt. And its getting worse. This product is STILL in stores, and it doesn't work. So now it's gotten so bad that the company doesn't even care of their products work correctly.
  
  So what happened to GM in the 1980s and continues to this day, is happening at Logitech. They make products which SAY they can do a lot, but in fact they don't ensure it by diligently creating and updating a product and drivers to meet changin demands. Since I've been on XP the entire time using this device, you'd think there wouldn't be any flaws.
  Flaws abound. Ironically, I use pretty standard sofware, Excel, Word, and IE browser. This mouse can't even handle those applications well.
  
  Sometimes the window doesn't pop up when you press the button, sometimes it does. Sometimes it pops up, and you select the application, and nothing happens. When this happens, if you do it twice it will work. Whoppty Doo, if I wanted to spend 60 seconds swiching applications, I'd have simply scrolled down the the bar on the bottom of my screen and bought a $5 mouse instead of this POS.
  
  This mouse isn't even a lemon, that would be giving it too much credit. It's just a sucky design that doesn' work as advertised.
  
  If you have to pay extra money to have Kye-Genius ship you a mouse that does application switch well, pay the money. That's the only way I know you can get a mouse with excellent application-switch functionality, and even THEY are starting to slip.
