A little disappointed 40 1

After a successful first experience with a mouse that mark, I wanted to renew with this model of form similar to the one I had before.
Unfortunately, I did not find the comfort, not because of the form but of sensitivity: it is still too sensitive about the end of the movement (syndrome "you do not know click" !!), and Furthermore, due to its laser on the back, when the pointer moves over the carpet lifts (it will not bother those who like me used to reposition their mouse regularly).
For the rest, no worries recognition, nice design, tiny connector that pulls over the mouse button off, auto power off, and presently autonomy flawless. The button below is used to change the speed of the rodent.
