Title: They won't get my money again
Review: I saw these and thought they would be worth a try. Unfortunately, the velcro lasts just about long enough for you to try the disks, then begins to fail. Within minutes on each of the three disks I tried, the velcro began to fail and couldn't hold the disk in place, making the disk completely unusable for anything but hand sanding. Seems like a fine idea that was poorly executed. I would be willing to try them again if they improved either the quality or amount of velcro used.
