  Best mouse I've ever owned

  by Zeffig232 on April 16, 2011

  Pros: Super-accurate, works well on a variety of surfaces, lightweight, silent scrolling, feels comfortable

  Cons: Batteries drain pretty quickly if you leave your computer on 24-7

  Summary: I love this mouse. To me, the most important feature of a mouse is precision. If your mouse is erratic or sluggish, it is like driving a Ford Explorer - ...

  Summary: I love this mouse. To me, the most important feature of a mouse is precision. If your mouse is erratic or sluggish, it is like driving a Ford Explorer - you feel like you're trying to steer a lump of Jello. If you're mouse is precise, it is like driving a Jetta or an RX-8. The drawback is that the batteries take a beating to keep this precision. Thankfully, there's a tiny power switch on the underside of the mouse. In my own experiences, I haven't found the mouse to go dead quickly, even with the button left on, but it could be because I don't leave my computer turned on all night long. (I suspect the mouse has some kind of feature to go dormant when it senses no signal coming from the USB Bluetooth transceiver.) I'm not sure about this, but I think the extraordinary precision is the result of two factors. Firstly, the mouse uses Bluetooth to communicate. (As long as you're not near a microwave or anything else that can disrupt Bluetooth, you're good to go.) Secondly, the sensor mechanism on the underside of the mouse seems to be built with a larger pick-up area. The hole is quite large and the LED is quite a bit brighter (and different color, blue instead of red) than most other wireless mice. The mouse works on many different surfaces, including on my molded white plastic table, on a shiny granite counter top, and even on glass. (The only times that I was able to trip the mouse up were by using it sideways on a clear window, or on a mirror.) I've occasionally experienced stray airborne cat hair accumulating in the sensor hollow, which I sweep out with a few brushes with my finger. I hardly ever use a scroll wheel, but when I do, I'm pleased with the smooth, almost silent scrolling of this mouse. The mouse is small but not too small, and is comfortable in my hands as well as my aunt's smaller hands. I'm puzzled why the posters of Jan 11, 2010 and Dec 3, 2010 had such trouble with this mouse. I haven't experienced any of the things that they mentioned. I recommended this mouse to everyone in my family.

  Update: This mouse uses a blue LED and 2.4 GHz frequency. I'm not sure anymore if it's actually using Bluetooth, or if it's using a proprietary technology with similar frequency. I saw "blue" in BlueTrack, and I know Bluetooth uses frequencies between 2400 and 2484 MHz, so I assumed BlueTrack was based on Bluetooth.

  Unresponsive and jerky

  by Villnius on January 24, 2013

  Pros: -Battery compartment has a pull tab. Took Microsoft a very long time to add this feature. It makes removing the battery easier
  -Comfortable. It's large for a mobile mouse, which might be good or bad

  Cons: -Jerky and unresponsive. Frequently gets jerky and freezes (old model 2000 wireless is much more responsive and reliable)
  -absolutely rubbish manual. Documentation is 3 pieces, in multiple languages. Only one page is actually about this mouse.

  Summary: I had bought this to replace an aging Microsoft wireless 2000 mouse. That was an old full size wireless optical mouse with the old hockey puck transceiver. Main reason what ...

  Summary: I had bought this to replace an aging Microsoft wireless 2000 mouse. That was an old full size wireless optical mouse with the old hockey puck transceiver. Main reason what that it didn't have the precision I was looking for.
  
  Too bad that old work horse runs rings around this piece of crap. The Mobile Wireless 4000 regularly stutters, slows down and sometimes just freezes for long periods, making it absolutely worthless as a mouse. The old 2000 model never had this problem and it was an RF wireless as well. The mini-dongle also doesn't have the range of the old hockey puck style that the 2000 uses. The stuttering, and freezing just gets worse if you move it more than a meter away from the dongle. The old hockey puck on the 2000 will receive and function from across the room (4 meters away).
  
  On the plus side, Microsoft finally put a pull tab in the battery compartment so that you can easily remove the battery (and the 4000 only requires ONE). On the old 2000, once you slide in the batteries, the battery compartment's hatch wasn't really big enough to get the batteries out easily, and there was no pull tab to help you. This alone isn't enough to warrant the purchase because ultimately, you'd want to buy this because you need a mouse -- to move the pointer around your screen and interact with the OS or games. This paperweight just can't do that reliably.
  
  Finally, the manual is a useless waste of paper. There's 2 pamphlets and a one sheet quick start guide. Only that one sheet quick start guide even mentions anything specific to the mouse and it basically only tells you where to stick the battery and the transceiver dongle. That's it. One's a thick booklet of legalese detailing the warranty in several languages. The other booklet is a very generic "product guide" that is about as relevant to this device as the instruction manual for a DVD player. It barely even mentions computer mice at all, and only in general terms. If they were going to kill a tree, I'd have preferred it if they actually devoted most of the paper to actually telling me about the mouse I just bought.

  Doesn't deliver on 10 month battery life promise

  by Abielantonio on November 24, 2011

  Pros: Very smooth scroll, atractive design.

  Cons: Battery wont last near 3 months. I have owned this mouse for approx. 6 months and have had to change the battery twice already meaning the mouse has used 3 batteries counting one that came in the package. Average life for each: 2 months, 8 hr/day

  Summary: Doesnt deliver on 10 month promise. Not satisfied with product, the mouse is also not confortable with big handed users.

  Not recommended until Microsoft improve battery life.

  by Sambal76 on September 6, 2010

  Pros: Excellent in functionality and physical design & size.

  Cons: Ultimately poor in battery life; Side programmable button is too far to be reached by the thumb (no good for right handed user).

  Battery life does not deliver on promises.

  by cnet_review on June 15, 2010

  Pros: Sleek-looking mouse with nice and comforable rubber-like grips on its sides. The matte surface is great for preventing fingerprint smudges and grease, giving it a clean look and feel.

  Cons: Very poor battery performance.

  Summary: The package promises 10+ months of battery life, but within my 1 month of owning this mouse, I have changed its batteries 3 TIMES. I turn off the mouse when ...

  Summary: The package promises 10+ months of battery life, but within my 1 month of owning this mouse, I have changed its batteries 3 TIMES. I turn off the mouse when im not using it and I use it for only 2-3 hrs a day for surfing the net. I do not use it for games or anything which may have caused the severe depletion of its battery life. My previous Microsoft mouse was on battery as well and each battery lasted at least 6 months for me then. Do not buy this product unless you are planning to have rechargable batteries in this.

  Probably the best mouse I've ever used

  by acm100 on May 21, 2010

  Pros: It works on every surface i've tried it on, it's receiver is tiny and won't be a nuisance , and it comes in a large assortment of colors. And the button on the side is neat!

  Cons: The scroll wheel is a bit too slippery for me, but some people like smoother scrolls.

  Summary: This mouse is the best one i've ever tried, i'd recommend it to anyone who wants to buy a mouse.

  Buy Logitech instead
  this is flimsy piece of junk

  by l0est on December 3, 2010

  Pros: Less than none

  Cons: cheap feel, horrible responsiveness, jerky
  Total mouse failure due to any number of reasons after a short time - buttons stop working, scroll stops working, laser stops working, wheel stops working, ALL OF THE ABOVE

  Summary: Buy Logitech
  M5 series for $
  M7 for extra nice
  MX for the best mice you'll find anywhere. <-that's PERIOD after that one
  You'll need to buy ...

  Summary: Buy Logitech
  M5 series for $
  M7 for extra nice
  MX for the best mice you'll find anywhere. <-that's PERIOD after that one
  You'll need to buy 5 MS wireless mice (due to mouse failure) for every 1 logitech m5/7 series and 10 or much more for every MX series. You're likely to be able to donate your working logitech MX series to your great, great grandchildren when you're 90 (assuming your just now entering kindergarten)
