I was expecting more out of these. At first it works really great, 5 stars but, after about 8 to 9 feet of sanding you start to think your not using it right because the quality starts to diminish. I started to have to tilt it around and use a little more force. I'm not a profession with the flap disc but I have used a few. I think I'm just going to buy Diablo flap discs from now on.
