Logitech MX Master 3S, Black

This is the third one I've bought. There are a few things you should know. First, if you're having thumb pain going up into your mouse hand, this is a cure; at least it was for my wife. Second, yes, it really does work on glass. Third, the lighter colored ones will start looking dirty over time. Clean them slowly and patiently with dishwashing soap, and they will come out like new. Do not try to scrape soil off because that can damage the surface.If you're not used to having so many controls, you'll probably learn to appreciate them. The only caveat is that all apps won't respond the same way to the same controls. I predict you'll love spinning the central wheel for speed scrolling.I make good use of the ability to switch quickly between 3 computers. It's the only way to fly.I've been using Logitech products since the advent of the personal computer. I've had mostly good experience. My only negative has been buttons wearing off their labels on the (very pricey) keyboards. Otherwise, near perfection.

This is the world's best mouse for professionals, such as SW developers, content creators, and any power user of a computer. I've owned one for four years. I've bought seven more to give to friends and family as gifts, even though they're pretty expensive. I am now those people's best friend. :)After four years the mouse is still in perfect working order and totally reliable. The battery life time on a full charge has diminished maybe 20% in that time. But it's still over a month per charge for me.I love the fact that the same mouse can talk to three different computers with the switch on the bottom, including iPhones and iPads. And I like the Logitech Flow software that lets me just move the mouse pointer to the edge of the screen and it changes the mouse to talk to the next computer over. That's pretty slick. I especially like two things about that. I can copy files from one computer to the other using ctrl-C on one, and ctrl-V on the other. This is by far the easiest way for me to copy files. The other thing is that I have a Logitech MX Keys keyboard, and when I move the mouse focus to another computer with Flow it also moves the keyboard focus. Perfect! I love it!The one caveat is that Logi Flow is not very reliable. I feel like I need to re-set it up every two weeks or so. The computers will just stop seeing each other in Options and I have to delete them and re-add them. Logitech, if you're listening, please fix this. If you can't find the actual problem and fix it, then just simulate what I do as a user to delete a computer and re-add it.

Couldn't do my day to day without it. I work in tech and this mouse is perfect. Battery life is great and it uses the same dongle as the Logitech MX mechanical mini.

Works great and love being able to customize per app

I used a Performance MX for over 12 years and absolutely loved it. I even replaced the left-click microswitch when it failed, but later, when the side back button started feeling stiff (a fair trade-off for a decade of daily use) I decided that it finally came time for a new mouse!I tried multiple options, but none felt quite right. Eventually, I landed on the Logitech MX Master 3S, and it’s been a great choice. The only reason I’m giving it 4 stars instead of 5 is that, while excellent, it doesn’t quite reach the “perfection” of the Performance MX (I really wish Logitech still made it!).The shape is nearly identical, but the Performance MX provided just a bit more support at the back of the thumb. Additionally, the forward and back buttons on the Master 3S are noticeably smaller due to the side scroll wheel, which I personally don’t use much—perhaps because of my large monitor. I would have preferred larger forward/back buttons instead.That said, I’m definitely nitpicking here. If I hadn’t used the Performance MX for so long, I’d probably consider this an outstanding mouse with a near-perfect balance of productivity and gaming functionality.Overall, it’s probably the best cross-over mouse you can buy!

Great mouse!

If you come from the 2S version as I did, it is an amazing upgrade. The best feature in my opinion is how quiet the clicks are specially if you work on design software surrounded by other people. Totally worth it!

Very comfortable, wireless, with a very long-lasting rechargeable battery, Bluetooth, vertical and horizontal scroll wheels, and two buttons for moving forward and back, for example, when browsing. It can be configured on three PCs, as it has three memory slots. Highly recommended.
