I'm certainly not a bodybuilder so I don't have the experience to say how good this grinder is but I can say it's lighter than my friend's more expensive grinder and it worked as good as his. This is better than hand sanding. Every do-it-yourselfer and, according to my professional friends, also enjoys this mill. She uses sandpaper, which I don't like. But for a few extra dollars you can get velcro if you want.
