I purchased the hand held sander primarily for sanding our old ceilings showing cracks at the joints and some poorly finished walls. The sander did a good job on the walls and was fairly easy to use. Dust gathering is superb. It came with a variety of grades of paper, but nothing course. All 180 and above which would be fine for new plaster, but only lasted a few minutes before clogging and having to change. The ceiling was a different matter entirely. The sander is very difficult to handle, bouncing all over the place. You really need to be on a high platform to hold it steady unless you have very strong arms and can only work an area of about a foot square at a time before moving position. All that said, it gave a great finish and I'm glad I bought it. Once I bought 80 grit paper, everything became easier.
