This grinder is more than good. I don't want to sand my projects as often as I would like as I can't stand the tingling in my hand, wrist and arm and having to wear ear protection every time I use a sander is annoying. This grinder is quiet, well balanced, shuts itself off after a few seconds, a very easy and efficient paper change! Dust extraction is great. I can't believe how little dust it leaves behind! (As in the previous posts, don't forget to clear the collection from each piece of paper). Now I am really looking forward to the resurfacing operation. I strongly recommend spending more money on this device than others!
