Review on 3M Air Powered Random Orbital Sander: Achieve Flawless Results with Precision and Power by Rene Putman

Although the grinder I received was obviously returned (packaging broken, dusty, dirty). This is a great grinder. I went with 5/16 hoping for a sander that can quickly remove wood without damaging it. This thing eats him. At about 1/5 the weight of my Festool, I know I'll be using it a lot. I think I will add less aggressive for the final cleaning.
