Discs don't hold well with velcro. You must use the full life of the discs before they expire for the velcro to not work properly. I think if there was more soft fuzzy stuff on the discs it would work 100% better, but there is almost nothing on the discs that wants to stay on a Rolock tool. They fly off or move before even half of the grinding wheel's service life has been used up. Like I said, if the company just adds some softness to the rims, they'll most likely stay 100% better. But for now, I'll never buy this money out the window again.
