Microsoft Wireless Notebook Optical Mouse 3000 -Slate Reviews

• Must have gadget for for frequent travellers...

  
  By A2A4OC6VGP7JSC on 2004-11-01
  My second wireless optical moue after Logitech 931152-0403 Cordless Optical Mouse. Much better than the Logitech mouse as it lighter and "soft"buttons.
  
  Highly recommended for laptops. Even though it has a "connect" button, never had to use it. Just plug and play installation. No need to download/install drivers. Used it with Win 2000 and Win XP.
  
  Pros ::
  
  * Solid responsive mouse
  * Soft buttons
  * Cordless so no tangled wires around you
  * Optical so can be used on ( just about ) any surface
  * Small USB receiver
  * * Used it, without any issues, with my wireless internet connection
  * Easy to replace batteries
  * Single AA battery
  
  Cons ::
  
  * Might be small for a person with large hands &/or long fingers
  * NO carrying case. Even though the adapter fits *in* the mouse. It could help to have a carrying case as well.
  * Not aware of any way to program the "buttons" ( for "left handed" persons )
  
  

• I love it!

  I'm a computer junkie, i have to admit that I fall for every gadget and gimmick that comes along when it comes to computer hardware. This was no exception. I recently picked up a new laptop and thought i'd compliment it with a new mouse. Whilst shopping, I noticed this little fellow on sale and thought what a great idea... the usb transmitter snaps in to the bottom of the mouse (also shuts it off so its not burning up the battery). Unfortunately the store that I spotted it at had sold out! I asked the clerk and he said the things were flyin off the shelves. Figured it must be worth a look so I went a few doors down to a competitor and found one.
  
  Great thing about buying hardware from the evil empire (Microsoft), is that it pretty much all works without downloading new drivers. Plugged the USB transmitter in, snapped the included single AA battery in the mouse (its located under the top cover btw if you dont like reading instructions like me), and it fired to life. Nice smooth tracking, worked on all surfaces i tested except for the actual screen of my laptop.. hehe
  
  All I cared about was to have an ultra-portable mouse that was wireless and worked well. I got the great bonus of, good price, easy to install, great function, perfect compatability. If it had two tumb buttons for fwd/back on web browsing, i'd write microsoft a thank you letter.
  
  

• Must have !! -- excellent product !!

• Perhaps the Ideal Laptop Mouse!

  
  By A2ZCXIZHS191TG on 2005-02-20
  
  I've had this mouse for a couple of weeks and am very satisfied with it. There was no software installation. I simply plugged the wireless receiver into an available USB port, put a "AA" size battery in the mouse, and turned on the computer. The mouse started working just as Windows XP finished loading.
  
  It may be a little small for really large hands, but it fits my hand (medium-size male) perfectly with my palm resting on a mouse pad for comfort. In fact, it feels better than most I've had in the past (desktop or laptop). And the mouse fits into a side packet of a laptop case very nicely. As others have pointed out, the USB receiver fits into the bottom of the mouse when traveling.
  
  The buttons are shapped well, as are the rubber side grips. The two large buttons feel solid, but the center scroll button is a little noisy and doesn't feel as well made. But, that center button works as well as the other two.
  
  Since I've only had it a couple of weeks, I don't know how long the "AA" battery will last yet. However, I'm using my laptop mainly as a desktop, used many hours each day, and the original battery is still going strong. To insert the battery, press the silver button directly below the "Microsoft" logo and the top pops off (the release button is designed to look decorative). At that point, one will immediately see the battery holder.
  
  The wireless feature works flawlessly. In fact, if one had really good eyes, one could operate the computer from the other side of a room. Yes, I've actually tried that, with the mouse moving the cursor around the screen with no problems.
  
  I just read one of the other reviews where a lag was mentioned. I've seen nothing of this. In fact, after reading that review, I sat here moving the mouse slowly, quickly, tiny movements, short movements, long movements, and so on, with no noticeable lag. The cursor moves exactly as the mouse moves.
  
  All in all, I think anyone would be satisfied with this mouse.
  
  ---
  
  UPDATE: I wrote the above in February 2005 and have continued to use the mouse since (now Aug 2006). It is still performing well and the battery mentioned in the review above lasted through about 2.5 months of routine everyday use. I have since purchased a second mouse for my desktop computer, which is also working fine after about four months. The following is in response to issues raised by other reviewers.
  
  To Edwin A. Pell III (New York), the mouse fits identically in either a left or right hand. To reverse the buttons, open the "Mouse" control panel and select "other pointing devices" in the drop-down menu listing your laptop's touchpad.
  
  Again, to anyone wanting to ADJUST MOUSE SETTINGS, use the "other pointing devices" selection in the "Mouse" control panel.
  
  To A. Mazakov (Fairfax, VA), the mouse is not sealed shut. The screws are located under the four black adhesive feet on the bottom of the mouse. Pry the feet off with a knife and stick them back on when finished with your modification.
  
  To Denis Dolgachev (Ann Arbor, MI), you do not have to disconnect the mouse each night. The mouse enters a battery saving mode when no movement is detected for some time, allowing batteries to last upwards of two to three months (depending on usage) with a continous connection. In other words, you really only need to disconnect the mouse when you want to move or store the computer.
  
  Those mentioning lags, delays, or choppy movement should check the "Mouse" control panel settings or for things interfering with USB devices. When setup and operating properly, there is no latency behavior whatsoever with this mouse. Movements are fine and precise. The only normal delay is in the split second when the mouse recovers from the battery saving mode after periods of inactivity.
  
  

• Great mouse with a few flaws *Edited - No flaws to speak of!

  
  By A2G1VOQFBEKJRX on 2004-11-28
  I've tried three or four wireless mice and have never found one that I like at all - they've either been floaty and unresponsive, or included ridiculously bulky wireless base stations that completely defeat the purpose of having a wireless mouse at all.
  
  This little Microsoft mouse solves these problems very well - it has razor-precise responses and communicates with the computer through a relatively small USB stub. The mouse itself is small, but not by any means uncomfortable. The USB stub snaps into the back of the mouse when it's not in use, which is a great idea and makes it truly portable (about the size of a small digital camera).
  
  The only problem is that the mouse doesn't have an on/off button on it, which makes me worry about battery life. The mouse does switch off whe the stub is snapped in (it has a tiny pressure switch like you'd find on a telephone), but there's no way to turn it off when you leave your desk is you don't unplug the USB connector. Maybe this doesn't actually effect the battery life very much (I've only had it for a few days), but I would have appreciated a manual on/off (and, as another reviewer already said, a carrying case).
  
  All in all, though, this is a great wireless mouse for portable or stationary applications. Microsoft may have its problems as a corporation, but nearly every Microsoft mouse I've purchased has been great, like this one.
  
  EDIT, March 2005 - I complained about the lack of an on/off switch, but this mouse has lasted for MONTHS on the initial battery. It seems to go to sleep when you're not using it, so there's no need to worry about switching it off to conserve battery. Truly an excellent mouse, I would give it five stars had I known this initially.
  
  
• Great mouse for a Mac
  By A37Q80MN9S5AZO on 2006-07-12
  One of the only downfalls of Macs, in my opinion, is that they only come with one-button mice. However, contrary to popular belief Macs DO support right-click, a very handy tool, I'm sure we all agree. All you need is a two button mouse that hooks up through USB and there you are.
  
  This mouse is especially great because of its portability. Obviously, being wireless helps in that regard, but the really neat thing about it is its snap-in reciever, which is about the size of a nail clipper, used to hook it up to the computer. This means that you don't have to fool around with a giant reciever when carrying your laptop around. In fact, there's not even any need to take it out. It doesn't add any extra weight.
  
  The quality of the mouse is top of the line. It's small, and feels very comfortable in your hand. It even has grooves in it for your fingers!! I've never had any problems with freezing, loss of signal, etc., and the battery life seems very good.
  
  I highly reccomend this mouse for MacBook users like myself.
  
  
• Good mouse, but poor battery life - needs a new battery every 10 days
  By A2V0I904FH7ABY on 2006-09-13
  When I first got this mouse, I was very excited that I can say goodbye to wires and the dust collection.
  
  Positives:
  - Good mouse, responds well to movement, clicks and double clicks
  - Ergo styling : Even though not as much comfortable as a bigger mouse, it is decent enough, I have been using it for 4 months now and I feel comfortable
  - Compact size : fits in a laptop bag without causing a bulge
  
  The mouse in two pieces, the mouse itself and a wireless transmitters that you plug into the computer. When not in use, the transmitter (which looks like a USB drive) latches into the mouse and switches off the mouse and thus saving power.
  
  When you want to use it, detach the transmitter from the mouse and this will power on the mouse and starts communicating which the transmitter which is connected to the computer.
  
  The way I (or any lazy computer professional) would like to work is to keep the transmitter plugged into the computer for the full time we work during the day (8-10 hours) and then at the end of the day before I pack my laptop, I unplug the transmitter from computer, latch to the mouse and packup.
  
  But, the problem is that if the mouse is 'powered on' for 8-10 hours a day for 5 days a week, the battery (Tried duracell and energizer) lasts only a week to 10 days.
  
  If you want to extend the battery life, power off the mouse by latching the transmitter back to the mouse whenever not in use like during lunch breaks, meetings etc.
  
  But I do not want to do that, will wait till a smarter mouse comes up that can manage its power well. I am not using this mouse for now, switched back to my wired mouse.
  
  
• Stopped working after 2 months
  By A1C5W37ILPSHIO on 2005-05-08
  My mouse stoppped working after 2 months. Very poor deisgn for the USB attachment. It sticks outside the notebook and by mistake if you tilt the notebook it damages the reciever.
  
  
• Great for the road warrior, but one flaw.
  By AN8O9TFN97JW1 on 2005-12-21
  I purchased this mouse about a year ago because I travel a lot. I am very happy with it for many reasons.
  1. Only requires 1 battery
  2. Switches off when not in use and receiver is inserted
  3. USB receiver fits into the mouse so you don't have to carry two pieces
  4. It's small but not too small (and optical and wireless of course).
  
  Improvements I'd like in the future but aren't needed.
  1. The battery cover and release button seem a bit weak, but I never had a problem with it though so I'd say it's negligible.
  2. Would love a 4th back button!
  
  Complaints
  1. The USB receiver is a bit flimsy. It was designed to pivot in case you need better reception, but I always thought it looked like a weak point. After 1 year, I have found that to be true. The receiver now has a weak connection due to the swivel point and if I bump it, the light flickers due to the bad connection and the mouse stops responding. I have to unplug it and put it back in to fix it.
  
  I do realize that I don't treat my electronics as nicely as I should and I have to pack up the mouse every day and travel on planes every week, but I'm still dissappointed that it's starting to fail after just a year. However, considering my situation and treatment in mind and the fact that I otherwise love the mouse, I still give it 4 stars.
  
  
• Truly Awesome Mouse
  By A2LFIEN1HSYFNH on 2004-12-29
  I travel with my job and use a laptop all the time. I received this mouse for a present, and I have to say it is a truly awesome mouse for several reasons. 1) Ease of installing - all you have to do is plug the adapter in a USB port and you are good to go, with NO downloading or anything. 2) The adapter fits in the bottom of the mouse when you are finished for easy packing. 3) The mouse is a perfect size for my hand and fits nicely in a pocket in my laptop bag. As I said, I travel with my job and have used many different kinds of mouses (mice?), and this is the best one I have ever used. I am very satisfied with mine.
  
  
• BOYCOT this product!!!
  By A15APNZDRPVHH4 on 2006-03-10
  Kinda harsh heading, I know. But I am on my 2nd mouse of this particular design. Great idea! HORRIBLE design! And I think they designed it this way knowing what would happen so as to increase sales.
  
  So what happened?? The USB dongle broke both times....it's all in the design. The dongle is essentially 2 peices, and the outer peice pivots (maybe for better communication with the mouse?...nah!!). The problem with the pivoting part is that it goes so far, and then breaks. The wires BREAK internally if you go beyond that point. Did Miscrosoft implement some kind of safety stop on the housing? Of course not!!
  
  BOYCOT!!
  
  They do make another one that is one peice...I will probably exchange my broken one for this (if I can - it's been a few months).
  
  
  
• Wonderful
  By A2NU9H8H5MJZSL on 2005-03-02
  I tried a number of corded and cordless mice for my notebook, and I settled on this one. It works. Plain and simple. The design is elegant (particularly the feature for storing the receiver at the bottom of the mouse). The mouse performs extremely well, even on some relatively difficult surfaces.
  
  
  
  
• Excellent mouse!
  By A2PY9RRSS52GQ6 on 2005-03-14
  I've owned this mouse for over 2 months, and I love it! It works on all but the blackest of surfaces. I love the way it stores: the connector just snaps into the bottom of the mouse and turns it off at the same time. This is a great little invention...
  
  
• Stopped working after 3 weeks
  By A1BPHTHG41HCI5 on 2005-06-09
  I happily used this mouse for 3 weeks. It then stopped working!
  
  It will respond sporadically, still; like if you try to use it, then it will move the cursor around on the screen a little bit. Also, if I click the mouse 5 times, it may register one of those clicks. But in other words, it doesn't work. I tried changing out the battery, but it doesn't affect it. It's still broken.
  
  A co-worker also had the exact same experience. We both recieved our mouse as a company gift, so we don't have a reciept, or anything to be able to take it back...

• Bad Design. Look for some other mice
  By A29PEIOWIBYE7V on 2006-03-10
  I bought this product in January 2006. It worked great untill the USB dongle stopped working apparently for no reason. I didnt dropped it or did anything that could have broke the USB dongle. This is my second bad experience with Microsoft Hardware. I will stay away from Microsoft's hardwares hereafter.
  
  
• Broken
  By A2R24WNZRD3A0Z on 2006-05-23
  For no reason whatsoever, this product broke after I had used it for less than 4 months... I did not get my money's worth.
  
  
• Great for students
  By AIVRS78LBI3VP on 2006-07-18
  I bought this item in the summer of 2005 to use at school with my laptop.
  
  Pros:
  ~ Size - it will fit in your backpack or pocket without a problem.
  ~ Easy to use - no downloading/installing necessary, just plug it in!
  ~ Receiver - snaps right into the bottom of the mouse so you'll never lose it! Also you can rotate a piece on the receiver to align it with the level of the mouse.
  ~ Battery life - I've had it for over a year and have only changed the battery once.
  ~ Cordless - I've used it many times when making powerpoint presentations, it's very handy to walk around with and just click and move on!
  ~ Durable - someone else mentioned that they wish it had a carrying case, I definitely disagree. This mouse doesn't need one! I've dropped it several times--once so hard that the top panel and the battery popped out--but it worked fine when I put everything back in its place.
  
  Cons:
  ~ Connection - it's not a very strong connection between the mouse and receiver, I've found that if the mouse doesn't have a direct line of sight to the receiver, it sometimes doesn't work.
  ~ Random behavior - a few times when I plugged the receiver in the mouse didn't connect. All I did was unplug and replug it and it worked fine though.
  ~ Size - some people with larger hands my find that's it's too tiny and uncomfortable to use. I suggest going to Best Buy or somewhere else to feel the different mice before purchasing them.
  
  
• Amazing battery life
  By AOEAD7DPLZE53 on 2007-08-28
  I have both versions of this Microsoft wireless mouse - Winter Blue and Slate. Just in case you're wondering: they are identical except for the colors, so you might as well choose which ever one is on sale. Of course if you need two wireless mouses, then it is best to pick one of each color. This way you can ensure that when you operate both mouses in close proximity, their wireless transmitters will not interfer with each others.
  
  What I found surprising is that this wireless mouse consumes very little power when it is in low-power standby mode. When you move the mouse around, the LED light brightens up, and current cunsumption jumps to about 25mA briefly. But once you stop moving the mouse, the current soon drops to only 0.4-0.5mA. Therefore you can expect a single AA alkaline cell (typically rated at 2800mAh under light load) to last for about six months, even if your never turn the mouse off. This kind of battery life is simply amazing.
  
  If you want to use rechargeable battery in this mouse, make sure you choose the latest generation of "ready-to-use" low self-discharge cells (such as Sanyo Eneloop or Rayovac Hybrid). Don't even bother with older generation 2500mAh NiMH cells from Energizer or any other brands, because those cells will completely self-discharge within a few weeks.
  
  One final remark: This mouse can be used under Windows XP without any software drivers. However, it is best to install the IntelliPoint 5.0 (or later) mouse driver from Microsoft. It gives additional customization features, plus a battery status monitor from your PC.
  
  
  
• worset mouse i have ever usd
  By A1C7JYXQ83V2UW on 2006-03-10
  this has to be the worst mouse i have ever used not only did it stop working at all just after one month but when i called microsoft and asked for a new one they told me that it os out of stock and i need to wait 1 month before i can expect my replacement.
  microsoft not having a mouse in stock what a load of crap.
  
  
• Wow
  By A19EFW4SWS6OJQ on 2004-11-04
  This mouse is just great. The reviewer before me pretty much covered all the major points. It has a much nicer feel to it than I thought it would. The material on the sides is great for grip, and overall it's just a reliable piece of equipment. I'd recommend it for anyone who either travels often or is short on desk space.
  
  
• I like it. No big qualms with this product.
  By A14YIWZMLE7F4C on 2004-12-04
  I've owned it for about a week and it has worked right out of the box on my Windows XP Dell 700m without any driver installation. It works perfectly with the receiver within a few feet and line-of-sight, but of course with some interference, the signal becomes intermittent. I cannot comment of battery life, but it shouldn't be a problem with some 2200maH NiMH batteries. (btw, it comes with a single Energizer AA). I like the fact that the scroll wheel now clicks like the Logitech mice. I believe the older Microsoft mice just had a smooth wheel. I would like to have a couple additional buttons by the thumb for going back and forward in browsers, but I knew that going in on the purchase so I cannot complain too much. The mouse is small and comfortable, but I'd like it to be a little more thin so I can stow it awhile easier. Also, it would have been nice with a carrying bag. But, at the end of the day, I think it is a great product.
  
  
• An awesome little mouse
  By A14VXKTBKGZ9SD on 2005-02-14
  The trackpad on my parents' laptop began to exhibit sensitivity issues, so they picked up one of these little mice. I've had battery-life issues with other wireless mice, and I didn't think that a mouse so small would be comfortable enough for extended use.
  
  Thankfully, Microsoft addressed my concerns. First, the wireless receiver snaps neatly into the base of the mouse when not in use, shutting off the sensor (and making for a neat portable package). Not quite a proper on/off switch, but an ingenious idea nevertheless. My full-size IntelliMouse Optical is still a better fit, but given the size, I can't complain. It felt fine in my medium-sized hand. I suppose it would be a little awkward if you have larger hands, but not totally unusable. And of course you get all the benefits of optical technology. The sensor is a little off-center, but this doesn't seem to affect accuracy at all.
  
  Anyway, I picked one up for myself. If you're a laptop user in need of a pointing device less awkward or problematic than the built-in track pad or "eraser head" pointer, you should too.
  
  
• A joy to use, Battery life is better than expected so far
  By A15I0U9WUAHGT9 on 2005-02-26
  I like using this mouse in my kitchen so much that I am getting a couple more -- To use at work and in my office at home (I hope that the transmitter range is sufficient). I don't have large hands so I actually enjoy using this mouse more than the larger, regular-size Microsoft mouse products. Since I only need the left and right buttons and the roller thingy, I don't need the extra features that the regular mouse products offer.
  
  I've been using this mouse since Christmas and the battery life is very good -- I haven't replaced it yet and have never "turned it off" be putting the transmitter back under the mouse. Since I use this with a laptop on my kitchen counter all the time, I am pleased that the battery life has been so impressive.
  
  Finally, I have always had the transmitter on the opposite (left) side of the laptop from where I use the mouse and it works just fine and I have never had a problem. So I am surprised that the other reviewer had to use a USB extension to get his mouse to work properly.
  
  
  
• Awful Experience
  By A3AX9H7PZ12EIC on 2005-05-22
  This Microsoft mouse stopped working after 4 weeks. The wireless connection would drop off. The rubber sides have started to wear off. I had the Logitech Cordless Notebook mouse for 12 months and it still works great. I am going back to Logitech.
  
  
• Great product, except for multiple unit cross-interference
  By A356CABMUJWBHM on 2005-06-15
  I have absolutely no complaints about this mouse, when I'm using it alone. When I'm sitting at a table with my colleagues, however, several of whom have the same mouse, it can be virtually unusable, because of interference between the units. It behaves like an old trackball mouse in those situations, which can be very frustrating.
  
  
  
• Great Mouse, But It's Dieing
  By A3FXW30S1VAVS3 on 2005-11-30
  I've had this mouse for about a year now and I find that it has now begun to die. After a year of constant usage, the reception in my mouse is getting bad. However, the battery life, and overall comfort of the mouse is awesome. I just wished that it would last longer then it has. Durability maybe the problem here but I don't know. I would suggest this mouse, but I would also like to warn that often when I used the mouse outside my house I would get interference often.
  
  
• Looks cool but overrated
  By A2KPQL8C7UCPJV on 2005-12-27
  Okay, on first impressions, this mouse comes out as a very neat gadget.
  
  Pros:
  * Small, compact in size.
  * Works with AA size battery as opposed to a charging station.
  
  Cons:
  * Having worked with Logitech's MX700, the wireless reception of this Microsoft mouse is definately horrible. The mouse becomes unresponsive once in a while.
  * If other people are using the same mouse in the vicinity, the signals get distorted and you occasionally loose control on the pointer.
  * Definately not recommended for gaming, as I've found out. Buy the Logitech one if you want a responsive mouse.
  
  In a nutshell: Its small, compact, portable ... Thats the only value it has. The functionality part is rather unimpressive.
  
  
• Good mouse for travelling
  By A163ZOLS97MJWQ on 2006-05-10
  I would recomend this product. It tracks well and buttons are nice. The rubberized sides feel nice too. Mine is a 2006 build, which comes with a different receiver then the one pictured. It doesn't have the extra movable piece at the end, but instead is just a stick, smaller then an average flash drive. I saw that one reviewer said there is no available software to program the buttons and that is true if you are looking for extra features, but Windows and Mac have the capacity to swith the buttons for left-hand users. In windows just go to "control panel" > "mouse" and then click the check box for switching the configuration to left handed mousing.
  
  Pros:
  Good Tracking
  Good signal distance for a notebook mouse
  Scroll Wheel works well (but see cons)
  Small and Compact
  Attractive design
  Small USB Receiver
  
  Cons:
  
  Small for big hands, but you have to know this when you buy it. It's for travel so being small is kind of the point.
  
  The scroll wheel works well, but it is the type that clicks, I was hoping it would have a smoother action to it, but I didn't have an out of box model to try out. This is a personal preference, but overall the functionality is exceptional and much better than many mice I have owned/used.
  
  So 4 stars, because I don't prefer the scroll wheel.
  
  
• New model not as good
  By A3ONE2VJCDI5GZ on 2006-07-05
  Unlike the product title, the reviews here are meant for the Wireless Optical Mouse, which looks identical, but not the newer 3000 as indicated by the name. While identical looking, they are vastly different. The 3000 has an improved 6-month battery life (which is the only plus). The new model removed rotatable antenna on the USB dongle, which is really bad. Even short distance, these mice still experience interference every now and then. With the older model, you can rotate the antenna and get a better reception instantly, but with the new model the only option is to try to move it to another USB port. The 3000 model also has "improved" tracking precision, which means very erratic unprovoked spantaneous movements of the pointer in real life. Lastly, the wheel is not "clicky" as the older model and much tighter. Overall, most of good things which made the older model very popular are no longer in the newer 3000 model.
