for the price, no worries: we have the announced features, the mouse surprises from the grip when you're used to desktop mouse, but we made it. Attention space for right-handed thumb is weak, one stumbles on the base, but just change hand position to not be disturbed, I got my thumb unconsciously now surelevé more than usual .

Otherwise no complaints, the DPI button works, and the mouse is nice design and feel
