MX Master 3S review: the queen of office mice quietly returns

Ergonomics

In terms of design, it’s very simple, the MX Master 3S is the same as its older sister. So we found its dimensions to be 124.9 x 84.3 x 51 mm, the pure design and the ergonomics that we already appreciated. Its weight is more or less the same (143 g) and therefore remains a heavy weight, which, combined with its large size, still does not make this a practical model for smallest hands.

Same design and as pure.

The hull always leans to the right to fit perfectly in the palm of the hand. Granted, the wrist isn’t as comfortable as a true ergonomic mouse like the Lift, but the MX Master remains comfortable. The soft-touch, ridged coating on the entire lower part of the hull provides good grip and the mouse cannot penetrate a hair throughout the movement.

The MX Master 3S has the same appearance buttons as version 3. In appearance only, because the main buttons are now silent! Logitech listens to reviews from users – and in our tests – who complain about audible clicks. The noise should be reduced by 90% (depending on the brand). It’s hard to measure actually, but like the Lift and the Signature M650, we can barely hear the pressure on the buttons, which is frankly pleasing, for our ears like our office neighbors.

Some have not changed. We found two secondary buttons on the claw level, reactive and now silent as well, as well as the button attached to the lower part of the shell, which is indicated by a small bar. The excellent MagSpeed ​​wheel inaugurated by the MX Master 3 leaves the choice between notched and completely free scrolling by simply pressing the button located at the top. It’s made of metal, like the secondary thumb wheel, which reinforces the mouse’s premium look and its poor build quality.

Many buttons can be configured in MX Master 3S.

So we can configure a total of 5 buttons-in addition to the two main ones-and the side scroll wheel to assign them functions and shortcuts. All of this is possible thanks to the new Logi Options + software, which we’ll get back to later. It has recently been simplified and is now more intuitive than the old Logitech Options.

Under the mouse, there’s the on/off button and the Easy-Switch button, Logitech’s in-house technology that allows you to connect 3 different devices and switch from one to another in a simple clicking. The Flow function is of course always available to navigate from one computer to another in a multi-screen configuration as if they were one.
4 PTFE pads ensure a perfectly smooth glide of the mat.

The mouse charges via USB-C.

A slight change compared to the previous version, the Unifying receiver is left in favor of Logibolt, dongle better safe-therefore more suitable for businesses-and is available in most of the brand’s latest peripherals. It is still possible to connect the mouse via Bluetooth, even if the latency has to be quite high. In terms of autonomy, we stick to the same standard: about 70 days of use, enough to see the future. A small LED at the level of the secondary wheel will turn red when the battery starts to run out of juice and you can use the mouse even when it is full.

How does grading work?

The MX Master 3S is without a doubt one of the best office mice around. Without making any in-depth changes to the series in design terms, it performs even slightly better than the MX Master 3, which is already at the top. Logitech corrected some minor bugs by implementing silent buttons. If you already own an MX Master 3, the change only makes sense if you’re distracted by its noise. For others, this MX Master 3S is an office model that we can only recommend.
