I snagged the offer at Amazon for a free ROS in part because a friend says that he keeps three or four !! ROSs loaded with a different grit paper mainly because the Hook and Loop facing on the sanding pad will "rip off" or "wear out". The fewer changes, the better the life.
Can someone confirm this or share your experience with changing the hook and loop material if it does wear out? Does it vary by manufacturer or is it a common problem with all ROSs?
