Sackorange 60 PCS 5 PSA Sanding Discs-10 Each of 80, 100, 120, 180,240, 400 Grit - 5 Inch Self Adhesive Stickyback Sandpaper Discs for DA Sander, Sand Automotive Car Paint, Woodworking Wood, Metal

Really good for woodworking, only used one pad since I bought it

The sand paper side is fine. Only the backing no longer sticks to the velcro after its removed. I have a box of hardly used pieces that no longer are useful on my orbital sander.

Don’t recommend.

This product is supposedly stick on sanding dic it does not stick , I wasted money buying the product. Big mistake

They peel off easily. The glue is of poor quality.

Sanding various wood types.

Long lasting and way cheaper then big box store

It gets the job done

I bought these to go on a 3M attachment for my drill, works like a charm, have been cleaning up an axe head. Only recommendation is while using, remember to clean the pads periodically while in use to keep using them longer (I blew through a few before remembering to do that)

I cannot answer a few of the questions. The pad does not stay on long enough to comment.
