Review on Sponge Interface Buffering Cushion Sanding by Andrew Pickering

First time with this product. Easy to apply to electric grinders I've used. The shoelaces are attached to the sliders with Velcro and the sanding sheets are firmly glued to the Velcro pads. Used to prepare the car's front bumper for painting. Works great! The only thing I didn't expect was that sanding inside corners etc seems to put a lot of stress on the sanding plate. My velcro and rubber came off on my DeWalt grinder, and the velcro came off on a Chicago Electric grinder I borrowed from my son. The product description should contain at least a mention, if not a warning. I ended up using these hand sanding pads and they compressed, shaped and cupped and they always returned to their original shape.
