Perfect to replace my old worn shoes (Above damaged following an opening of the mouse to repair), if they have a perfect glide, much less grip than with original pads, the cup is remarkable, despite a comment I have seen here no problem thick (They exceed well enough that the bottom of the mouse does not touch the support on which it is based).
It fit perfectly in the locations and installation is easy foolproof. I recommend this purchase, those of the Logitech store certainly cost only 2 but the FDP (10 if I remember correctly) are too high, here we have two games to 10 FDP understood. Do not hesitate.
For the seller: ultra fast delivery (And that comes of Germany!).
