MX Vertical Ergonomic Wireless Mouse, Multi Device, Bluetooth or 2.4GHz Wireless with USB Unifying Receiver, Graphite Black

Very good mouse for my hand rest

it has a software support to change the buttons in each application on your desktop

Got this for my wife who has to click through a load of menus at work and was complaining about fatigue in her mouse finger and the wrist due to the repetitive nature of tasks (and clicking). Read a bit about this mouse which is supposed to solve such issues with an ergonomic grip and taking the strain of the hand and wrist area. Was a bit skeptical at first given the price but it is worth the cost as now my wife's hand and wrist strain issues have gone and as a bonus many people who come to her office also compliment her on the unique mouse!

it has a good haptic feel and - after a little familiarization period - works very well. I used to have the MX2 before. What I really miss is the scroll mechanism of the MX2 to change the scroll speed by the automatic release of the internal "brake"of the scroll wheel. Besides that a very ergonomic piece of technology - as you would expect from Logi.

I've been using this mouse for over a year and a half. and hands down the best mouse I've ever used. At first, it felt a bit strange. But, after a day or two I got used to it. It's a bit pricey, but I feel it's worth it.

Comfortable to operate and the battery charge appears to last a while (still on the initial charge after a few weeks and shows the battery as full). Horizontal scroll works well on excel, but you need to get used to it a bit. The only downside of the mouse is the awkward position of the back and forward buttons on the side. You will slowly get used to it though. Update: After using the mouse for more than a year, I have barely used the vertical scroll wheel. If you are buying this for excel, you most probably wouldn't be using its features most of the time (Except for the infinite scroll which is pretty great). Still, I feel a lightweight mouse would have benefited me more.

Logitech MX Anywhere 2S is part of my travel kit which I use as multi-device and multi-function mice with my Macbook 12" and iPad Pro. Its is for sure pricey but worth the money which helps with my work efficiently and the features improves productivity. Highly recommended for travel as it is a small package with great customizable button features, pair with up to three devices, long lasting battery and a sensor that works on nearly every surface.

I've been using ergonomic mouses like this for years, however, this is easily the most horrible mouse I've ever had the displeasure of using. The grip is atrocious, requiring a conscious effort to hold the mouse, with a tense hand. This is because the grip area is thin, and worst of all, the mouse buttons are flat unlike any other ergonomic (or even regular) mouse.
