I find the mouse well. It lies well in the hand and clicks the left and right mouse buttons are as good as gone. At least it does not bother anyone more when I click like crazy. Mouse wheel and two buttons at thumb make noises, but does not bother me, because I use this rare. Something strange is yet to get no feedback when you press the mouse button. For the wireless I give 5/5 because it works great. the coverage is great. Battery life I can not judge. Have any case for a month, the same batteries and use the mouse constantly. The mousing is satisfactory, the scan seems good but a very precise guidance is difficult. It does seem that the cursor jumps something repeatedly. However, it works on virtually any surface. As Gamingmous I find it inappropriate.
