The Logitech MX Master 3S continues the popular Logitech MX Master line of high-performance computers. It retains same ergonomic shape and feature set, but features several notable improvements over the previous generation Logitech MX Master 3S. This version features quieter buttons and an improved sensor with wider CPI range, making it more suitable for use with higher resolution displays.
It also uses the new Logitech BOLT receiver, which promises improved performance in congested wireless environments and stronger protection than the old Unifying receiver used in previous MX Master models. The Logitech MX Master 3S offers just a few changes from its immediate predecessor, the MX Master 3, upgrading to an 8000 DPI sensor from a 4000 DPI sensor, moving to quieter (but less tactile) switches, and using a key Logi Bolt instead of Logitech Unifying Receiver.
Still, the $99 Logitech MX Master 3S is the best wireless mouse for productivity, largely because of what it retains from the previous model: a fantastically comfortable grip, solid build quality, Logitech Flow software for moving the pointer between different devices, and plenty of customization options with the powerful Logitech Options+ app. Whether you’re looking for a mouse to help you code, edit videos, crop photos, or just get the job done, this mouse is hard to beat.
Design
The design of Logitech MX Master 3S has not changed much. Placed next to the MX Master 3, it’s very hard to tell the difference between the two, especially if you were using the previous model. The texture of the left and right buttons is new, but it also looks plastic compared to rubbery texture of the Master 3. The rest of the top surface of Master 3S is covered in the same rubbery material as the old one. Another change is new color option called Pale Grey, which is quite different from the Mid Gray color that was available on the MX Master 3.
In terms of ergonomics, the new MX Master 3S is still as good as the MX Master 3, with the same level adhesion due to the top silicone layer. The mouse is quite large for a small hand but comfortably fits medium to large hands. The layout and feel of the customizable side buttons is the same as before. Yes, it still takes some effort to press the gesture key, which is located under the thumb. The main MagSpeed electromagnetic scroll wheel on the Logitech MX Master 3S is the same as before.
It is a pleasure to use and very quiet. There were times when I forgetfully left the scroll wheel spinning while scrolling through long web pages, only to realize until I touched it with my finger. It also stops quickly thanks to the magnets clinging to the well-machined aluminum roller, much like disc brake calipers on a motorcycle.
Comfort
The Logitech MX Master 3S has very comfortable shape for the right hand. The buttons are well placed and the materials are of very high quality. There is also a rubber coating that covers the large thumb rest, the palm area and the entire right side. Overall, this is a pretty large mouse that can be cumbersome if you have very small hands.
The beautifully designed mouse will fit most hand sizes and different grips, although some are designed for specific grips. A mouse with a higher back is likely to be better for palm grip, as it offers more surface area for resting the palm of your hand, providing a more comfortable feel. On the other hand, something with a short and flat design is likely to be used for fingertip grips.
There is no best or worst grip, it all depends on how you prefer to hold your mouse and what shape, size or weight you prefer. Each grip has its own benefits, but if holding the mouse with an unwanted grip causes pain, then it should not be used as it can lead to wrist injuries such as carpal tunnel. No mouse is truly universal for every grip and hand size, and there is no perfect mouse that fits all.
Connectivity
Like its predecessors, the Logitech MX Master 3S can connect to up to three devices wirelessly and quickly switch between them using the Easy-Switch button on the bottom or the Logi Flow feature in the Logi Options+ app. You can connect via Bluetooth or a Logi Bolt dongle. One Logi Bolt dongle, which is already pre-paired with your mouse, is included in the box, but you can also use a dongle you got elsewhere if you pair it with Options+.
You don’t need Bluetooth pairing software, which is important because only Windows and macOS can run the app. Please note that the MX Master 3S is not backwards compatible with Logitech’s Unifying Receiver, which was the pre-Bolt dongle standard used with the MX Master 3S. Logi Bolt is also not backwards compatible with devices that work with the Unifying Receiver.
The company switched to Bolt from the Unifying Receiver because Bolt offers better security and lower latency, especially in environments with a lot of wireless devices. But if you’ve invested in multiple Logitech devices and don’t want to use multiple USB ports for those devices, the transition will still be a challenge.
Performance
One of the most important changes introduced with the new Logitech MX Master 3S is the inclusion of an 8000 DPI Track Anywhere optical sensor that can accurately track movements on more complex table surfaces, such as glass. This new sensor is also twice as sensitive as its predecessor, and according to Logitech aims to speed up the workflow of creative professionals working with 5K and 8K monitors.
However, it’s unlikely that the average person working with a standard 1920×1080 display will ever feel the need to increase the mouse’s DPI to the 8000 mark. Compared to its predecessor, the Logitech MX Master 3S’s battery life has remained unchanged it’s claimed to last on a full charge. approximately 70 days.
Unlike its direct competitor, the Razer Pro Click, the Logitech MX Master 3S has USB Type-C charging port located on the front of the device. This also means that on those rare occasions when the mouse’s battery life reaches zero, you can continue to use it while it charges-take that, Apple’s Magic Mouse.
Battery Life
Logitech estimates battery life for the Logitech MX Master 3S to be up to 70 days, the same as the MX Master 3. We didn’t have time to verify this claim, but after about a week of wireless use, Logi Options+ reported that the battery was still at 95 percent capacity.
The MX Master 3, which has been our daily driver for several months, seems to need a new charge every 6 weeks or so. The good news is that if your MX Master 3S runs out of power, you can use it while charging. Just keep in mind that it requires a wireless connection to your computer to work, even if it’s connected to a network.
Final Words
The Logitech MX Master 3S is a great mouse for office use. It has a comfortable ergonomic shape with a thumb rest and is exceptionally well built. It connects wirelessly via Bluetooth or the included USB receiver and can connect to up to three devices at the same time. You can customize sensor settings, program custom gesture controls, and remap buttons using customization software.
