The mouse fits comfortably in your hand. The double-click button in my opinion is superfluous because it is inconveniently located. Since I've used faster forefinger twice. On a mousepad it is going very well, but it is not accurate to each other underground. The push buttons could also slightly more backpressure tolerated because they cause very quickly. If you could turn off the LED lights, then that would be nice, but it's not what makes the mouse worse now.
I would give it 3.5 stars actually, but that's not possible, yes. Therefore it is a bit better off than I feel.
