30 Pack 8 PSA Sanding Discs Set - 5 Each of 80, 100, 120, 180,240, 400 Grit - 8 Inch Self Adhesive Stickyback Sandpaper Discs for Drywall, Floor, Woodworking, Metal

Some sending discs did not have their grade specified, I had to guess.

Not much to say about this except it does what the seller says it will do.

Good

Great product. The only thing I didnt like was how thin the backing was. When I would pull it off it would sometimes rip and make it to where I had to pull several pieces off. Just annoying.

Sand great but sticky on back is weak starts to fall off when not in use for a week, but re adheres while sanding.

Mine are not self stick. I think they sent the wrong one. Mine need a velcro surface to stick too.

These pads don’t stay stuck to the wheel. I have to re-stick them every time I go to use them. Otherwise, they do their job as intended.

will purchase again when needed

With the first one I tried, the adhesive was all lumpy after peeling back the paper so it would not have been flat on the disc - threw it away. With the second one (same grit), I got it on but it would not stay on, kept peeling off - threw it away. Third one (different grit), it went on, stayed on, and works fine. So maybe some grits are okay, some are not, dont know, but Im expecting to get 50% yield at best. At the price, maybe thats okay if you dont mind wasting the time messing with the bad ones.

THe problem is not with the sand paper, but with the glue that was selected. Large gobs of glue are left on the 8 sanding disc and its nearly impossible to remove. Im throwing that paper out.
