The loss of flexible touch plastics may seem a degradation at the beginning, but I largely prefer unleashed plastics for long -term use: my MX Master 2S has developed unsightly smooth spots on the two mouse buttons where the soft coating has been high, and other long -term users have pointed out that the coatings become sticky over time.

The two primary mouse buttons and the scrolling wheel are almost dead. Despite this, they still have a clear feedback with a separate bump and no feeling of dough. In Clinet mode, the mouse wheel has a notable bump between each parchment. In smooth mode, the wheel has just enough resistance to be easily controlled, while turning freely.
The horizontal scrolling wheel on the side is definitively scrolling smoothly and has much more resistance than the primary scrolling wheel. This allows greater control of the wheel and helps protect against accidental scrolling when moving your thumb. The scrolling is incredibly smooth, without any capture or scratch, and the striated texture of the aluminum wheel is comfortable and easy to handle. Click on the wheel is still quite noisy, like any mouse. The three side buttons and the upper button have a mute click, and it is not disruptive.
Despite weighing 150 grams, this mouse is easy to slide around a surface. The feet are smooth, easily sliding while having enough friction for precise control, and the sculpted shape facilitates movement and uprising. Although high weight means that it will not be ideal for competitive and high intensity games, the shape is preferable for longer sessions, whether you are grinding dungeons or you slip through spreadsheets.
The sensor is capable of 8,000 points per inch, but most people will probably leave the sensitivity below. I had no problem with the recording, leap or tremor of the inputs, and the sensor was incredibly precise on all surfaces, even frosted and transparent glass.
Gesture controls and haptics

The gestural commands of the MX Master 4 are one of its most important characteristics. These were presented on each generation of the MX Master Line, with only small changes across generations. The gesture control button was previously located at the bottom of the thumb rest, hidden below the surface of the rubber, but was now moved to a standard button on the side, which I found more comfortable and natural to use.
