  • Really great sander. Easy to use
This is a really good sander. The adhesive discs peel off easily and it gets outstanding revs. My only complaint is that the price is not competitive as you can get the exact same Dewalt sander at Home Depot or slight less $$.

  • Nice tool
It works as it should, only down side was it was really dirty in the box it's was sent in (like sand). Fortunately the air port had a cap on it, so the sand/dirt didn't get inside of the tool.

  • sanding pad is junk
sander feels good in the hand and runs smooth.....but go ahead and by a replacement backup pad with the 5/6-24 thread with this sander as it will break off the stud within the first few uses. Everyone of these I have ever bought does this. They made a nice sander and put a cheap backup pad on it to save money I guess. ... show more
