Unlike Logitech's MX Vertical, the MX Master 3S isn't formally an ergonomic mouse, despite its curved shape being specifically designed for right-handers. Although its all-terrain Darkfield sensor has been enhanced from 4,000 dpi to 8,000 dpi, which is more than sufficient for making quick movements over a huge 4K panel or numerous monitors, it is not a fast-twitch gaming mouse with an astounding 16,000 dpi resolution.
Logitech MX Master 3S ergonomic design and features
Rather, the 5-ounce wireless mouse, which comes in black, dark graphite, or mild gray and is composed of either 22% or 27% recycled plastic, depending on the color, focuses on versatility and productivity. The latter stems from its electromagnetic scroll wheel, which adjusts resistance according to your scrolling speed or pressure, and its Logi Choices+ software, which offers an almost limitless number of shortcuts and customization choices (more on that in a bit). You can do the same thing with deliberate movement or a finger flick, but a little button beneath the wheel switches between precision and free-wheeling scrolling.

Pros and Cons
Pros:
- Remarkable comfort and battery life
- Perfectly precise electromagnetic scroll wheel
- Ultra-customizable for different apps
- Works with multiple devices and operating systems
Cons:
- Lefties need not apply
- No place to store the USB dongle
- Fans of tactile clicks may prefer the older version
Logitech MX Master 3S weight and dimensions
There are several scroll wheels besides that one. There is a large horizontal scroll wheel on the left side that is controlled by your right thumb in addition to the top button, the main left and right buttons, and the clickable chrome wheel. A curving wing, running board, or thumb rest that supports your hand in a slightly slanted posture is located beneath it, along with two tiny buttons that by default navigate your browser forward and backward. If you move the mouse up, down, left, or right and press down with your thumb, a gesture button that looks like a little line (like a raised hyphen) on the wing will add four more functions.
The only other modification to the MX Master 3S, aside from the crisper sensor, is that the main clicks are now almost silent—90% quieter, according to Logitech—and difficult to detect unless you put your ear close to the mouse. I thought the buttons were perfectly comfortable, but if you prefer a hard tactile sensation, you might prefer the still-available MX Master 3.
The mouse's dimensions remain constant at 4.9 by 3.3 by 2 inches, and it feels incredibly comfortable and natural as soon as you place your palm on it. To trigger the gesture button, I had to move or push my thumb more intentionally than I had anticipated, although the side buttons and scroll wheels were easy to use.
Wireless connectivity
The MX Master 3S raises the standard for wireless convenience. It makes use of the integrated Logi Bolt USB receiver or a low-power Bluetooth connection. Similar to Logitech's previous Unifying receiver, the latter connects to a Type-A USB port and barely protrudes from it. It also connects to one of the company's MX keyboards over a 2.4 GHz link.
You may switch between up to three devices with various Bluetooth or USB connections using a button on the bottom of the mouse. Logitech's Flow technology also allows you to copy and paste between systems and transfer the mouse from one screen to another, such as from a Mac laptop to a Windows desktop. One small complaint: If you're preparing for a trip, there is nowhere to store or carry the receiver on the 3S.
Charging and Battery life
The mouse includes a USB-C-to-A connection and a USB Type-C port for charging on its nose. According to the business, a full charge lasts up to 70 days, and a one-minute plug-in delivers enough power for three hours of use. However, based on my observations of the Options+ battery gauge, I believe full-time users will need to plug in every 15 to 20 days. (Logitech gets a thumbs up for being environmentally conscious by employing an internal battery rather than throwaway AAs.)
DPI settings and button customization
Speaking of Options+, it provides almost infinite customization options, such as the ability to remap buttons and navigate between tabs in the browser using the side scroller.
Additionally, it offers as many preset or custom combinations as you might want for button assignments for various programs, including Adobe Photoshop and Premiere, the Microsoft Office suite, and the Edge browser.
With its 8,000 dpi sensor and silent buttons, Logitech's flagship MX Master 3S Wireless Mouse is only a click or two away from being flawless.
Pros and Cons
- Remarkable comfort and battery life
- Perfectly precise electromagnetic scroll wheel
- Ultra-customizable for different apps
- Works with multiple devices and operating systems
- Lefties need not apply
- No place to store the USB dongle
- Fans of tactile clicks may prefer the older version

The Conclusion: What's Better Besides Mind Control?
Undoubtedly, the majority of PC users do not require a $99.99 mouse, and it is unfortunate that Logitech does not provide an MX Master 3S for left-handed users. It's difficult to envision a superior pointer, though, until the day comes when we can move our cursors only by thinking. It doesn't get any better than this, whether you're utilizing Undo and Paste commands at the speed of thought or scrolling through 1,000 lines in a second.
