3M Xtract Net Disc 310W, 180+, 5 in, Die 500X, Pack of 50 Hook and Loop Sanding Discs, Virtually Dust-Free, Value Option for Metal, Wood, Composites, Stock Removal, and Fine Finishing

Brilliant discs when used with an orbital sander. The stock removal is very impressive and makes every job really fast.

Too thin, ruffles and pulls away from back plate. The Velcro is not strong enough.

These really are better than the cheap red disks. They sand quicker and leave a smooth finish with no swirl marks

I was using cubitron 2 710w, I found this is almost half the price and seems like it works a bit better at least for 120,220 and 320. Yet to test 80 grit as I have a full box of 710w

These disks are the bees knees. The dust collection is superb, they stay sharp the longest I’ve been able to find. The sanding quality they leave behind is second to none. I mean they’re actually worth the money cause they last so much longer. They stick to the pad real strong, so never slippage. The blue color is kinda cool but most importantly makes sanding a breeze and finishes come out so spot on I would be hard pressed to try anything else. Mostly using on woodworking projects as a profession

The sandpaper is great, no issue there, all the reviews about dust collection and effectiveness are true. But... I was using a 6" Bosch ROS and was humming along just fine, quite impressed with the performance of this sanding disc. When I went to change the disc, though, for some reason the second sanding disc wouldn't stick to the backing pad of the sander. Turned out all the hooks (of the hook and loop system, the loops being on your sanding disc) of the backing pad were gone! After reading up online I found other people have had the same problem. The mesh on these is loose enough that, at least with some sanders, the hooks poke through to the business end of the disc and get worn off. Backing pad's for 6" sanders aren't cheap... I now have a new backing pad and a "pad saver" coming. Hopefully the combination will last a bit longer. At least I'll just ruin a pad saver next time, instead of an expensive pad. So! Bottom line, great performance, great discs, but use a pad saver so you don't ruin your sander like I did.

Best sandpaper. Good price. Really enjoying them.
