Its pros: Ergonomics. Lies in the hand like a glove. The buttons are pressed a little louder than we would like. The DPI button has a backlash. I liked the lid on the magnets, no stupid latches that get loose. With its cons: The cursor sticks, the receiver is only 20 cm away, in line of sight. I didn't like the slide at all. On a flat, hard surface, the mouse wobbles slightly from right to left. The slip strips are glued very poorly, around the perimeter of the stickers there is glue that collects all the dust, plus I had to warm them up with a hair dryer to slightly move them to the position as in the photographs, but it was much worse. The back sticker is broken in one place, as if they tried to peel it off and glue it again, although I bought the mouse completely packaged, not opened, with all the seals.
