Logitech’s MX series has always been the go-to mouse for power users that want excellent tracking and customization to make life on Windows (or Mac) easier. The company’s latest, the MX Master 2S aims to amp that up by introducing Flow, which allows you to copy and paste files and text between three PCs simultaneously with ease.


I never owned or used any of the MX mice before, so the MX Master 2S is my first introduction to Logitech’s popular series. At first glance, the 2S seemed a little too big and clunky to me, but surprisingly, the large belly and generous thumb support feels supremely comfortable to use. It doesn’t look like Logitech has changed much over the previous generation in terms of design, and that’s completely fine by me, as the 2S is one of the most ergonomic mice I have ever used.

Much like the MX Master, there are seven buttons on the 2S: left, right, center, back and forward, scroll mode shift, and gesture, as well as two scroll wheels. The second scroll wheel and the thumb buttons took a while to get used to as they are quite tightly placed together, but after a week or so of use, I was reaching out to them without any errors. Each of these buttons are fully customizable, including the gesture button under your thumb, which you must hold and move the mouse up, down, left or right for additional commands. Clicking the button once is set to switch between window panes by default, but that of course can be changed - we will cover this in the next section.

For the MX Master 2S, Logitech has packed a 4,000dpi Darkfield sensor (up from 1,600dpi) that seemingly works on all surfaces, even clear glass. I tried the mouse on a cloth mouse pad, wooden table, paper, a leather journal, my jeans, and it had no problems tracking whatsoever. This is an important tool in 2S’ repertoire as it will be able to tackle any surface in a workplace, making it extremely handy to take around for meetings and presentations. In terms of normal use, the MX Master 2S tracked on most surfaces quite well but it wasn’t as accurate as I hoped it would be. Maybe I am conditioned by the years of using gaming mice, but I found the 2S a little laggy. It’s not a deal breaker by any measure but it’s something to keep in mind if you plan to do any accuracy-based work or gaming with the mouse.

In terms of battery life, this has been improved from 40 days to 70 days, although I did not have a chance to test the mouse out for such a long period of time. The small battery-level indicator on the left never dropped in my week of use. Logitech also claims that the mouse will run for an entire day on just three minutes of charging, which again is something we could not verify in our limited use. Thankfully, unlike a certain Apple mouse, there is a micro-USB port on the front of the mouse so you can charge the device while using it.

Features and Performance

Like the MX Master, the 2S can be either used as a wired mouse, or wirelessly paired with up to three PCs simultaneously. The mouse can be connected via the included Logitech Unifying USB dongle (which can also pair up with a variety of Logitech wireless keyboards), as well as via Bluetooth. Most modern laptops and desktops come with Bluetooth built-in so you won’t necessarily have to buy a separate dongle for it. There are three tiny buttons below the mouse that lets you shuffle between the connections, although I wish these were placed on the surface. If you are someone that plans to move around different connections repeatedly, lifting the mouse and clicking on the button every time can become tiresome and frustrating.

This is where Flow comes into play, which not only lets you move around different PCs without having to manually shift the connection, but also allows you to transfer files and text between them with ease. Setting up the Flow is pretty simple: once you have paired the mouse with the PCs, installing the bundled Logitech Option software and recognizing the device is all it takes to make it work. As long as the PCs share the same network, you will be able to move or transfer files like images, documents, video files and more quickly, and also carry over any copied text. Sliding the mouse pointer on one side of the screen transfers the control over to the other PC, allowing you to smoothly control any of the three connected computers. It all works remarkably well, and simplifies the entire workflow for anyone who has to operate on multiple computers at once.

Coming over to the gestures, I found them to be quite clunky to implement in my daily use. With gestures, you can perform basic tasks like minimizing all windows, snapping windows on the left or right side, etc. but the problem with using these is that the travel distance required to register a gesture is quite large and there isn’t a way to change that. So, I have to click the gesture button and make a large swiping motion in either direction to make the gesture work, instead of a doing small flick motion which I feel would work much better and feel less awkward. Regular use might get you used to it but it was not something I found to be intuitive.

The MX series is also known for its innovative scroll wheel and Logitech has implemented the same tech for the 2S, as well. The scroll wheel can be switched between a ratcheting action to a free-spinning scroll, which can be particularly helpful to zoom through a large document. In the free-spinning mode, the scroll wheel will continue to spin for as long as you want, and stopped at a second’s notice, giving you complete control over it. The scroll wheel also implements the SmartShift technology which automatically switches to the free-spinning mode if you tug at the scroll wheel harder than usual. The SmartShift tech can be a bit too sensitive but thankfully that is customizable through the Logitech software.


The Logitech MX Master 2S’ biggest asset is Flow, which honestly works better than I thought it would and gives power users an effective solution to simplify their workflow. Elsewhere, the MX Master 2S is a solid all-round device, with fantastic ergonomics, a powerful sensor that tracks on all surfaces, and offers a ton of customization. Is it worth the upgrade from the MX Master? There doesn’t seem to be any big difference between the two in terms of features or performance, so unless you’re specifically interested in controlling multiple devices with Flow, then I would stick with the MX Master.
