Review on 🛠️ TEMO 100 pc 1/2 Inch Coarse Grit Sand Drum with 2 pc 1/8 Inch Mandrel, Compatible for Dremel Rotary Tools by Sam Bell

They seem about as good as the Dremel brand sanding drums I buy at the hardware store and a lot cheaper. They keep the same time and seem to be the same from one roll to the next. I'm a blacksmith and these are useful for cleaning serpentines and other handle parts. They work reasonably well on very dense hardwoods such as Catalox, Ebony and Lignum, as well as annealed and hardened blade steels. A single drum might not last long under heavy use, but with a 100-pack and using a quick-change mandrel, I didn't make too much of a fuss. And as far as I can tell they last as long as Dremel brand drums. Very good value for money.
