I need a small grinder to get to a hard to reach place. This will work great. Unrolls quickly as expected. Rear muffler, all-metal construction with rubber grip, feels good. My compressor is small but recovers quickly and the grinder is small enough not to stress the compressor. It comes with a set of good wheels and 2 collets 1/4 and 1/8. The work I need to do will most likely involve cutting/grinding metal, so I'll probably need to use a different tool, but at least a smaller collet will fit. Don't allow enough torque to remove it if it's too tight. In general - very satisfied.
