the mouse had been used and the pads were not so hot the new pads were exchanged Kinderleicht against the old. For me this has been worthwhile, I have virtually a new mouse. In the delivery 2 sets are included so you can replace the pads again. The only drawback, the company Com-Tra shipped for 2,49 by letter but the real shipping cost is 58 cents. :-( 1.91 cost certainly not a standard envelope ;-)
