I would highly recommend this to anyone not wanting to spend alot of money on a porter cable or other high speed buffer. I bought it at wal mart, don't remember how much it was, and it works great. I'm sure it is nothing compared to the PC's, but If you just want to buff your headlights or wheels, this is the way to go. I used them on my headlights, and it worked great.
