I work a lot with 3D graphics and play games, so an accurate, comfortable and nimble mouse was very important to me. In general, after the purchase of this mouse, I was very pleased. I advise. Has pros: - Feels good in the hand - convenient software for setting up additional keys - The wheel is pressed left and right, in general, the buttons are conveniently located. - The sensor is just super - Convenient charging cable. Some cons: Sometimes I touch one of the additional keys (when trying to find the mouse in the dark)
