Disappointed, the Logitech MX 1100 is much older but still well above. Certainly here we have 6 buttons but tendinitis in thumb will be in the program if you want absolutely every use, very wrong place. 6 programmable buttons are rather hard and noisy, really pleasant to use. Given the number of buttons as close we would have hoped for a different feel with at least one button 2 to locate better but not anything. The MX1100 had easy access button on the handy thumb, nothing here. There is also no activatable free wheel, notched only mode. To work in 3D is really not practical. For now the battery conso looks correct but I have not for a very long, difficult to judge.
Only positives: -The Application to program the buttons depending on the software used is quite nice -The Coating of the mouse is very pleasant to the touch and provides good grip -The Two sensitivity adjustment buttons allow you to choose really the desired sensitivity in a bearing, over a light indicates where we are, it is very clear.
In short the positives are to be given for the "gadget", in terms of the important points of a mouse is all missed.
