Logitech MX Master 3S Wireless Mouse, Ultra-fast Scrolling, Ergo, 8K DPI, Track on Glass, Quiet Clicks, USB-C, Bluetooth, Windows, Linux, Chrome - Graphite

i have carpal tunnel and i’ve tried many an ergonomic mouse over the years. this one is my go-to. i’m now on my second one. the first one lasted me several years; the reason i replaced it was the left click was having issues of being frequently non responsive. i looked it up and some others had had the same issue, and apparently for them blowing gently under the left button fixed it, but not for me. it got mildly better when i had it wired in instead of using it wireless, but didn’t fix it completely.despite that, i can’t even knock off a star for it. it lasted plenty of years in my opinion and it’s just so comfortable and high quality.

I have owned the MX1 - the previous model now out of production - and it lasted 10 years. I upgraded to this mouse and it continues where the last left off. Customizable buttons, custom scrolling, responds to twitchy movements which is also adjustable.As a previous comp gamer- May be a little heavy for constant gaming, but I know a lot of engineers use this mouse for CAD work and for actual comp use 10+ hours a day.Large size is good for bigger hands like mine (I’m 6’0), and helps with proper hand position for carpel tunnel.Battery life is measured in days or weeks - I charge on the weekends.Don’t get a bad little $15 mouse in your 20s, thinking you’ll never get carpel tunnel. If ur an engineer, take care of your wrists and hands, it’s how you earn your living. Stop planting. This mouse will help.

This mouse is lightweight, larger than a computer mouse you might find at a public computer but smaller than the logitech MX pro rollerball mouse. The grip feels comfortably rubberized and very ergonomic. There is ample space for the backward and forward buttons, side scroll wheel, and the button built into the palm rest. None of the buttons can be easily pressed accidentally but are close enough together as to be accessible.The mouse buttons truly do possess a quiet click, along with a satisfying tactile response. The same can be said for the other buttons on the mouse. The scroll wheel is a simple joy to use, "ratcheting" and smoothly spinning as the usecase demands. No longer is my scroll intermittently too short or too long, whether I am navigating a menu in a video game or scrolling to the recipe on one of the several million interminable blog/cooking sites. There is a dedicated button to switch between scroll modes which I personally find redundant, but it can be mapped to many other functions.I had been toying with the idea of adapting a rotary encoder to scroll horizontally, but the thumb wheel on this mouse is much more convenient. Such a wheel should be standard on every mouse, given the sheer volume of scenarios in which horizontal scrolling is required. Now it is far easier to scroll through a browser window while performing another task in the other half of the screen. Excel is far more pleasant to use as well.The mouse has very good connectivity, supporting the proprietary logitech "bolt" adapter which is bundled with the mouse, bluetooth, and wired connection. The button on the bottom of the mouse allows a user to switch between three separate devices seamlessly, each of which can have their own profile. I noticed no difference in speed between the logitech receiver and bluetooth, but the mouse was close enough to the PC as to render the difference negligible. Latency in wireless mice has been nearly imperceptible for some time now, and this mouse is no exception.The logitech software has a simple UI, allowing the user control over all facets of the mouse. There is an interesting "Gestures" feature which is activated by holding the button in the mouse grip and moving the mouse in a cardinal direction. I find it to be a gimmicky feature, but appreciate its inclusion. Overall the design of the mouse is well thought out and maximizes the comfort and productivity of the user.

I’ve been using the Logitech MX Master 3S for a couple of weeks now, and it’s hands-down the best mouse I’ve ever owned! The ergonomic design is super comfy, fitting my hand like a glove, even during long work sessions. The quiet clicks are a game-changer—90% less noise than the MX Master 3, which is perfect for shared spaces or late-night work. The 8,000 DPI sensor is crazy precise, gliding smoothly on any surface (even glass!), and the MagSpeed scroll wheel is a dream for zipping through long documents or spreadsheets. Switching between my laptop and desktop via Bluetooth or the Logi Bolt dongle is seamless, and the battery lasts forever—still at 80% after heavy use! If you’re looking for a productivity beast, this mouse is worth every penny, especially if you snag it on sale.

One of the best mice of all time. This is my second MX Master mouse after giving my original model away many years ago to a friend. It’s very solidly built, intuitive to use, and endlessly customizable. I’m grateful that Logitech has finally honed in their Mac driver software which used to be pretty glitchy and resource-intensive. That was the #1 thing making me hesitant to get this mouse again. Thankfully their Options+ software is finally usable, intuitive, and saves your user preferences via your account (though I wish it could be used without an account!) between computers. The mouse is fairly usable/customizable in macOS even without it though—System Preferences will allow you to set various functions to many of the mouse buttons by default. However the full functionality and customizability of the mouse such as scroll inertia, control of the magnetic dampener, and hot functions, are all only available if you use the software.
