They are very helpful in removing grit, dirt, paint, rust and other materials.

Worked great for polishing dirtbike parts to bright finish. They burn up pretty fast, but that is to be expected. Will buy again.

Perfect for cleaning motorcycles and other small parts. Nice

They're very durable

Great deal for the price.

A really nice selection of polishing wheels. No way to identify what's what, as far as grit levels. You just have to go by feel ... good luck with that. I do like them and I'm sure I'll find many uses for them. Really good price too. Recommended.

I was kind of skeptical at first but these do a excellent job on aluminum heads，they are somewhat durable.

Very handy for polishing all kinds of materials. Great for removing rust.

These are high quality..GREAT for deburring threads on aluminum parts after machining process. I will be buying more of these.

I was surprised be caused these performed just as well as the much more expensive brands.
