It works great, and the legs in it are like new after six months of operation, the case is without scuffs, all functions work. The buttons are short, the move is clear, there is no looseness. I don’t like that dpi is not displayed anywhere, and you yourself need to understand what mode is set, but there are 4 of them, and catching the right one is not a problem at all. The wheel is comfortable, small, but scrolls well. I advise.
