This grinder is fantastic. It's lightweight, much shorter than an electric grinder, putting your hand much closer to the sanded surface for more control and less wrist strain. It has a speed dial (right-handed) that gives you extra control over your sanding. The self-generated vacuum is incredibly strong. I would have liked a longer hose to keep the pouch away from the work area, but it can be purchased separately. Even though the grinder uses a moderate amount of air (cfm), make sure you have a good compressor if you plan on grinding for a long period of time as this could damage your compressor.
