I was very pleasantly surprised by this mill. We bought our house 4 years ago and it has heavily textured walls; Since we were repainting room by room, we decided to remove most of the texture. Before I got this sander I made 2 bedrooms by spray painting and scraping the walls with a trowel and then using a standard drywall sander. Finally, now that we have to paint the common room, I've decided to bite the bullet. and try an electric grinder to see if it reduces manual labour. Boy did it ever do! A wall that used to take me 2-3 hours to finish was done in 30 minutes with this thing! I was concerned that this would create a lot of dust everywhere, but it really isn't. With bright LED lighting, you can see any dust flying off the grinder head and it's minimal. I was also concerned that it would be difficult to hold the grinder level against the wall at full power, but that wasn't a problem as the tool itself is lighter than I expected and the pivot point between the handle and the grinder head is a lot well designed. It pivots easily and naturally, providing consistent contact with the wall. I'm no longer afraid to detexture the rest of the house! What a relief! A very happy consumer here.
