It actually collects the dust and you have to empty it fairly often. The quick stop is useful and saves time. Wish the on/off was under my finger rather that in the front. Read morePublished 5 months ago by John T.

A little heavy for one-handed extended work, but plenty powerful.Published 13 months ago by Dr. Fuller
I used this sander 3 times and on the third time it started to pulsate and then it died. I guess all the other reviews were right. Read morePublished 14 months ago by C. Tramonte
This sander works really well and does a great job. I was using an older Dewalt sander and bought this one after reading the reviews. Read morePublished 15 months ago by John
The low profile is easier than the one we have that is the older model. It oasted a long time, but finally quit. Hope this one performs that long.Published 15 months ago by regetta Lancaster
This thing sucks up debris like a BOSS. Quiet, OK to maneuver, but feels so high quality that I'm pretty sure I'll be using this sander for the next 3-4 years. Read morePublished 15 months ago by Stephen George
