Logitech introduced the MX Master 3S mouse, which is an updated version of the popular MX Master 3 model. Visually, the MX Master 3S is very similar to the MX Master 3. A rather aggressive right-handed device design is complemented by a pair of scroll wheels (one for moving up / down, and the other - left / right). On the side surface there are three buttons, which can be interacted with using the thumb.

One of the main differences from the previous model is the presence of a sensor with a resolution of 8000 dpi (MX Master 3 uses a sensor with a resolution of 4000 dpi). According to the manufacturer, the left and right buttons of the new mouse are 90% quieter. When you press the mouse button, the tactile sensations are preserved, but the sound is more muffled. Despite having a higher resolution sensor, the mouse is intended for office work rather than gaming, mainly due to its comparatively low 125Hz polling rate.
