Review on 🔧 POWERTEC 45004 A/O Hook and Loop 8 Hole Disc, 5-Inch, 40 Grit, 25 Pack by Glenn Cartwright

Cutting action 40 grit very bad. They may last a minute. They won't become smooth in a minute, but any cutting action will disappear immediately. After 5 minutes, the velcro is smoothed out, the disc simply flies off and no longer holds. I thought $7 for 25 discs would be okay, even if they're awful because I can just keep changing them, but I was wrong. Their main problem isn't that they wear out very quickly (which they do) but that these discs can't sand wood.
