Lenovo600 Bluetooth Silent Mouse, Blue Optical Sensor, Adjustable DPI, 4 Button, Microsoft Swift Pair, Windows, Chrome, GY50X88832, Gray

I’ve had pretty good luck with Lenovo products. For those who don’t know, this is the company that took over when IBM exited the consumer computer business and sold it in 2005 to this Chinese company. Wisely they didn’t do a lot to mess thing up, their laptops are still among the best on the planet and they make keyboards that still have that famous IBM touch, or at least something very close to it. And so it is with mouses (or mice if you prefer). They have a good variety of them, including the GO series which is about as close to a good old days mouse as you can get anywhere.WHAT YOU GETThere are a few variants of this series and unfortunately someone made the poor decision to lump them together on this page which means that the reviews are all mixed together. Look at the fine print at the top of each review to be sure that you are looking at the right one because several models are so similarly named. This one is the GY51C21210 which uses a Type C dedicated (not Bluetooth) dongle that plugs into your desktop or laptop computer. It is rechargeable with non-replaceable batteries and the only unique features are a three-way variable DPI button and a user-programable button that by default works as a volume control. More on that later. With it you get a recharging cable but no transformer and a helpful but not perfect instruction sheet.FIRST IMPRESSIONSThis is a relatively small mouse but not super slim, I think it’s small enough to travel well with a laptop and large enough to be my main mouse for my desktop computer. If you switch between computers you have to take the previously mentioned dongle with you. Fortunately thanks to an easily removable cover with a magnetic release there is a nifty slot inside to store it. The mouse is not ergonomic and less rounded than most modern ones and has the timeless design of a left and right finger activated tap button and a simple rubber scroll wheel. The DPI button is on top but not in the way so I found it can’t be accidentally activated in normal use. The one and only other button, and I am so thankful for that, is a button under your right thumb that by default you hold in and turn the scroll wheel to use as a volume control. I try to avoid mice with any buttons other than the default standards of left, right and scroll but if I had to pick just one function for an extra button it would be as a volume control, it comes in handier than I ever expected.CUSTOMIZATIONAs simple as this mouse appears it is deceivingly customizable. As soon as I plugged the dongle in it automatically paired (there is a manual pairing button on the bottom of the mouse) and a popup window suggested installing an optional unifying app which can give you additional customization options like changing the number of DPI steps, changing the rate for each press, or disabling the button completely. You can also customize the side utility button to be used for a variety of conferencing calls and a few other handy options.IN USEI had high hopes that spending this much for a simple mouse that I could get from some no-name brands could get me one that feels well made, has a blue laser for better tracking and does what a mouse is supposed to do. That last one sounds simple but as a graphics professional finding a good pointing device isn’t as easy as it sound. It seems Logitech’s ads are everywhere and most people choose them because they offer so many mice that sound cool, and these days cost a lot. I have bought their mice for years and I have resolved never to do it again. They are legend for not lasting and the last one I trashed was supposed to be one of their premium models – it was non-stop frustration from day one, always doing unpredictable things while I was trying to concentrate on my work. My initial thoughts about this one from Lenovo is like night and day – it tracks perfectly with no lag, skip, erratic movements, etc. Each button has just the right amount of tactile click to it, the plain vanilla scroll wheel is light years more accurate than the loud fancy one on the Logitech. The single side button is mounted where I can reach it if I want to but never accidentally. But this is not an ambidextrous mouse, the utility button would be almost impossible to reach for a lefty.YES NO MAYBEThe price bounces around on this for some reason but I got it at a right time, you can actually get it for less at the Lenovo site but this was more convenient. I’ve been using it for a while now and my hands are neither large nor small and I’ve adapted well to the fit. The most important thing is that it is 100% predicable, when I reach over and put my hand around it everything is where it should be and the buttons feel just right. When my pointer moves it goes just where I want it to every time. With countless mice models out there choosing one is a very difficult task but once again this brand seems to know how to get it right in their own quiet way. I am very happy with my selecton.

Sleek, smooth and easy to hold. Best mouse I’ve had! It glides smoothly along the screen! Great functionality and accuracy!

Just a great solid product. Well worth the money.

After my old Large Microsoft mouse died and no longer is being made, I began searching for a replacement. For my XXL hands I wanted a physically large mouse with a prominent palm swell. The cork thumb surface and prominent palm support of this Lenovo ergonomic mouse caught my eye, so I purchased it. It has the bells and whistles of a Logitech. I thought the 45-degree angulation was a bit of a gimmick, but since my mouse resides on a pull-out shelf to my far right, this orientation made my wrist and forearm feel somewhat more at ease, less contorted (but only in retrospect). For some reason, now unknown to me, I continued my search and found a lovely white, German-engineered Cherry mouse, also large and with a prominent palm swell, but with less extreme angulation, so I made that my final selection ... the pinnacle of mouse design, if you will. Funny thing, however, is that I didn't remove the Lenovo dongle from my computer and find myself not infrequently switching off the Cherry and using this Lenovo mouse again. It's almost as if my right hand is trying to tell my head that this is the one you should be using!

Perfect. I used it on a glass table and works perfectly, is really easy to Connect and quiet

Needed a mouse with a reasonably sized type C connector, and to my surprise the options were very limited. But this one is great. Small but comfortable. Battery lasts long and recharges fast. Tracking is great, no noticable latency.

Excelente mouse, silencioso y cómodo

Where to start with this lousy mouse. I was excited to try a more expensive, well reviewed vertical mouse. Well it's been a year. To start with, this mouse has always been ergonomically painful, and I say this as someone who has been using vertical mice for years. The thumb mold is too far in, and I ended up having to custom mold and glue in a Bondo-o shaped piece to make it work. This wouldn't have been too bad, except for all the other issues:1) The scroll wheel already jumps and misses "clicks" and goes in reverse less than a year later.2) The tracking has always been lousy, and has only gotten worse over the year of use (I've repeatedly cleaned the lens area).3) Speaking of the lens area, it is not well sealed and it will pick up dust and hair and cause more failures.4) The mouse occasionally loses connectivity, even with the dongle less than three feet away.5) Your options for DPI appear to be (very sensitive, so insensitive as to be worthless)6) It eats through batteries, requiring a replacement about once a month.On every single level this mouse has failed. I am replacing it shortly, and I can't wait to send it to the rubbish bin where it deserves to be. I cannot believe such an expensive mouse can perform this poorly. Do not buy this mouse, whatever you do.
