Design

Measuring 124.9 x 84.3 x 51 mm (HxWxD), the MX Master 3S is quite hefty at 141g but feels natural and ultra-comfortable to use.

The Logitech MX Master 3S comes in Graphite, Pale Gray and Black color options. The mouse has a matte-textured finish and is made of high-quality plastic with some of it coming from post-consumer recycled plastic. The mouse is designed for right-handed users and is intended for a palm grip.

The MX Master 3S transmits data via a USB dongle that can be connected directly to the PC. Alternatively, it can also connect via Bluetooth. There is a USB-C port located on the front side which can be used to recharge the mouse or to use it in wired mode.

There are a total of 7 buttons on the MX Master 3S, all of them can be customized using the Logi Options+ software.

At the top are left and right click buttons which we found to be very precise, crisp and quiet during our test. Located here is the excellent MagSpeed electromagnetic steel scroll wheel that is quick and precise with just enough resistance.  The scroll wheel itself is clickable and can be used to assign a function.

Right below the scroll wheel is a button which is set by default to set the scroll wheel mode either ‘Ratchet’ or ‘Free Spin’. It can be customized to switch DPI on the fly and supports two presets.

There two buttons are on the left side of mouse along with a thumb scroll wheel and a small indicator to display charging status. Right where the thumb rests are the final button which can be used for different OS gestures such as viewing open applications.

At the base is a toggle switch to switch between wireless and Bluetooth mode. There is also a tiny button here to pair and switch between 3 devices. Finally, there are four small PTFE, one in each corner, to help with smooth, gliding movement.

Overall, the construction is fantastic and the MX Master 3S looks premium and ergonomic, it feels comfortable to use and glides smoothly. However, the included USB Type-A to Type-C cable is not braided and feels a bit cheap.

Features & Performance

The MX Master 3S Wireless comes with Logitech’s Darkfield Laser Tracking sensor and features a maximum of 8,000 DPI. The sensor offers accurate tracking with sensitivity adjustment options in 50 DPI steps.

Another highlight is that the mouse uses a built-in battery instead of replaceable ones, which makes it hassle-free. The USB-C port on the front side of the mouse can be used to recharge the mouse or to use the mouse in wired mode.

The default DPI settings on the mouse can be customized using Logi Options+ software. It can also be manually switched using DPI button below the scroll wheel (once set via software).

In our everyday test, the mouse performed well and with very good overall impressions. It can be easily adapted to your own preferences and skills with the Options+ software.

In addition, we never noticed any connection or delay issues. The main buttons click very precisely and feel light and crisp while being incredibly quiet. The side buttons, are easily accessible and the matte, textured surface offers a very good grip.

The scroll wheel is also excellent and can be adjusted to free spin or in Ratchet mode where you can feel every scroll. The horizontal scroll wheel is useful especially when you want to scroll between different tabs in Chrome. However, we felt the thumb button to be a little weirdly placed and inaccessible.

Software

Mouse settings can be adjusted via the Logi Options+ software which can be downloaded from Logitech’s website. The software allows customizing the button functions, adjusting scroll wheel settings, setup Logi Flow, back device settings and more.

The mouse supports the company’s Flow technology, which lets you use and control multiple computers seamless. Simply switch to another computer by moving your cursor to the edge of the screen. Or copy files from machine and paste on the other. Something to note is that Logi Flow works only runs on devices that have Logi Options+ installed.

When paired with one of Logitech’s keyboards such as MX Mechanical, the same mouse and keyboard can be used across multiple PCs.

Also lets you create app specific button functions for software’s such as Adobe Photoshop, Adobe Premiere Pro, Final Cut Pro, Google Chrome, Safari, Zoom, Microsoft Teams, Word, Excel, PowerPoint, and Edge.

Battery & Charging

In terms of battery life, Logitech promises up to 70 days of use on full charge or 3 hours of use from a 1-minute charge. While we couldn’t test it for full 70 days, the mouse was fully functional for about the 30 days we used it from a single charge.

Verdict

The MX Master 3S Wireless is a fantastic wireless mouse built for productivity and versatility. It comes with an excellent battery life and the built-in battery helps avoid replacing them every now and then. If you are looking for a high-end, ergonomic wireless mouse for use at home, office or on-the-go, Logitech MX Master 3S Wireless is a great choice and it is incredibly quiet.

The only minor downsides are the average quality of the USB cable and no built-in slot to store the USB dongle.
