I have buffing wheels and compound that I use on one end of my grinder, and while it works well, lots of times it is not practical to use. That's what I wanted these smaller wheels for, so I could bring the buffing to the job rather than the other way around.The wheels are okay. I used my compound sticks that I use with my grinder setup because I am familiar with how they work. (Some other reviewers have said the compound included with this set is pretty good so I might try it next time.)Buffing wheels don't have a long life span (that's why they are so messy to use :-( and these are no exception. I don't have any other small buffing wheels to compare to so I don't know if these are good or bad. Just don't expect a very long life.
