Review on Efficient Orbital Sander Pneumatic Action Polisher: A Must-Have Tool for Pro-Level Finishing by Daniel Russell

Consumes a lot of air. I was using a 29 gallon porta cable two stage air compressor and the grinder blew too much air. The grinder actually worked quite well, but only lasted 5-6 hours and then stopped completely. It is not durable and not designed to work on small or medium sized air compressors.
