For the most part these discs have worked out great. I use them to polish rough rock, harder then marble and concrete and they have done the job brilliantly. The velcro on the headpiece pealed loose the first time I used it, but I super-glued it back down and have not had an issue since.
I initially started using these on a non-variable speed angle grinder, the velcro does not hold well at the grinder's speed and the pads slip, causing an oscillation that unbalances the grinder. I picked up some 5/8" (may be 1/4") course-threaded screw-rod from Home Depot and converted the head pieces for use in a variable speed drill, I have not had an issue with it all and the work fantastically.
