hi, i still have that (by then pricy) wireless logitech. its very old, with a 2 buttons wireless mouse with a ball. it went through several moves, gravity tests but works perfectly beside, most my keyboards (on other machines) last long, very long. on the other side, i have to buy 3 or 3 keyboards per year per machine for my wife & kids. mostly killed by the mug or the soda even a rather expensive one sold as 'spill resistent' did not last long the P O R N keys by me are ok, the G A M E S ones show more usage ;-)
