Microsoft MAIN-35956 Sculpt Ergonomic Mouse (L6V-00001)

I've been using this mouse for about 3 years now. It is an awesome mouse. Very comfortable and ergonomic. Battery life lasts a long time. I've replaced the AA batteries maybe 5 times in 3 years. Tracking works well/smoothely, as expected. Some things I've noticed that are worth being aware of (these don't bother me much, but I imagine they could matter to some folks): * The glossy black surface will tend to collect grease from your fingers over time. It's very noticeable against the shiny black and is kind of nasty. Luckily, it also cleans off very easily (I tend to use an alcohol or clorox wipe). * The black skids on the bottom glide smoothly on the surface of my desk, but they also leave behind black residue on the desk surface over time. My desk's surface is plastic fake wood so I just wipe it off with a wipe every once in a while (takes some scrubbing). If you have a real wood desk, you may want to use a track pad instead. * The connectivity of the dongle can be bad if there is a lot of metal near the receiver. For example, I used to have a metal padlock on the k-slot right next to the USB port where the receiver dongle was plugged in, and that seemed to mess with the connection a lot. On the other hand, plugging this into the back of my monitor seems to work just fine. * On macOS the windows and back buttons do not work. They work find on Windows and Linux.

Before this, I have been using the Microsoft Sculpt Comfort mouse for over two years. It has lasted well, but caused me some minor joint pain with my middle, ring, and pinky fingers with extended used. So when I needed a second mouse for a new laptop, I decided to try the Sculpt Ergonomic mouse instead. In short, I would recommend the Ergonomic mouse over Comfort mouse and might retire the Comfort mouse early in favor of a second Ergonomic mouse for my desktop. For the Comfort mouse, I prefer the slightly less stiff wheel and recognize it might be a better choice for either people who want a more traditionally shaped mouse, or people who want more mouse shortcuts (two swipe gestures and a button vs. the Ergonomic mouse's one customizable button), but the Ergonomic mouse is much more comfortable for long periods of time and feels like a more premium product. Although I've had it for less than a week so far, the Ergonomic mouse is much more comfortable. It's larger, a little heavier, and seems to have a little less resistance on my desktop (although that might be just because it's new). The base and battery cover is magnetic which is nice, but not an important difference. It also has a USB receiver instead of using bluetooth, which means I can more easily use it on different computers without the hassle of a bluetooth pairing screen, but could be a problem if you already are short on USB ports or don't want a bump sticking out of your laptop. The Comfort mouse also had occasional hiccups in connectivity (which might be due to my setup), but I haven't experienced this with the Ergonomic mouse. Overall, both are good, but a mouse should first and foremost be comfortable and reliable, and the Ergonomic Mouse is more comfortable and more reliable than the Comfort mouse in my experience.

I am a knowledge worker who regularly spends full workdays in front of the computer. And since I am also working on a part-time CS master's degree on nights and weekends, I spend even more time in front of the computer than the average person. As I scaled up my career and began spending more time in front of the computer, I started to suffer minor wrist pain due to keyboard and mouse usage. Most keyboards and mice are usable by the majority of people who do not spend inordinate time in front of the computer (e.g. if you spend less than 4 hours per day on the computer, you can probably get away with anything). But I conducted a lot of research about ergonomics and bought a few products. By far the best products have been the ones coming out of Microsoft's hardware group (amazing, I know). I don't work for Microsoft, but my theory is that a small team of ergonomic experts in the corner managed to develop some great hardware and Microsoft somehow allowed them to bring their products to market. I use the Sculpt Ergo Mouse at work and at home. I have not had wrist pain ever since switching to this mouse. I additionally use the MSFT bluetooth Sculpt keyboard which can be purchased in a set with the mouse (the mouse and keyboard are both bluetooth and can be bound to the same black thimble that you put into the computer). You need to get used to the weird ball shape, but the shape forces you to hold the mouse in a healthy way. No more of those dumb wrist pillows (those simply adapt crappy hardware to healthier standards). This mouse has ergonomics built into the design. Also, it somehow lasts for months on two AA batteries. I cannot remember how often I need to change the batteries, but it's so infrequent that it does not bother me at all.

The BEST mouse I ever owned. It truly met the definition of ergonomic, without symptoms of carpal tunnel or added stress on my finger and hand joints. I wish the mouse was not decommissioned.

Solid, but expensive

Esse é o melhor mouse que já tive. Uma pena que parece ter saído de linha pq nem a Microsoft tem. Mas, felizmente, esse vendedor tem, e por um preço caro mas bem menor que outros raros vendedores, o que fez a minha alegria. Veio super rápido ... agradeço e recomendo!!!

Al principio se siente un poco raro por la forma del mouse, pero una vez que te acostumbras, es el mejor que he probado. Muy muy cómodo, suave al tacto y responde rápido.

Beats using a traditional mouse, and perfect for my palm size. The transmitter is larger than the keyboard's and would prefer using a single transmitter for both. Not too much of info available online about this, but yet to install the Microsoft Mouse and Keyboard center.
