The mouse has a killer feature - a hardware change of buttons for the left hand, which makes it easy to change hands during operation. Pros below: The main advantage of this mouse is the hardware inversion of the buttons. No settings, special drivers and programs are needed - the mouse switches to the left hand simply by pressing the side buttons. Accordingly, it is suitable for working with any system. Cons below: A year later, the side rubber inserts peeled off. Carefully re-pasted for a moment - enough for a month at most. I don't know what to glue again :( And without them it is inconvenient.
