These sanding discs have terrible adhesion. I got one to stick to my alcohol-cleaned 8 aluminum power sanding plate by heating it up a little with a light touch with a torch but a week later its lifting off and is causing unsquare sanding.

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.

I tried two of the 8 discs to stick to the wheel with less than perfect results. I scraped, sanded and cleaned the disc with acetone and still poor results. After letting the first disc set for several days I discovered it had dis bonded and slipped down from the wheel. After using rubber cement all is well.

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

Look just like the original disc that came on my 8 inch porter-cable sander, very nice! I got the assortment and a smaller pack of the most used grit.

Just what I ordered

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.
