This grinder works great. It's a little heavy and tires your hands (however, lowering the sander to clean the sandpaper holes gives you a break and your hands are ready). A vacuum cleaner works better. . I would buy disposable vacuum bags from the store, that also helps get rid of the dust. This reduced the sanding time for the 18x31 blanket by more than half. If I used 100 grit sandpaper instead of sanding grids, it would reduce the sanding time even more. I wouldn't use 80 grit unless you have a ton of dirt to sand off. It works even better on walls because of the ergonomics of how you hold it. One thing I would like (I would definitely change) is a handle and hose. The situation when you sand ceilings. It seems like the handle and hose have to be reversed when you make the blankets. Another useful item you might want to use is your work belt, tool pouch, or shoulder strap (e.g. for your eater). Use one of those straps, burlap, etc. around your waist to support your sander, especially when working on blankets. I hope this helps you decide. I'm not a drywall professional, but have been renovating and renovating homes for about 30 years. Our current home was built in 1920 and I had to buy this mill 3 years ago to help with all the rooms and ceilings we have finished. By that I mean we took the laths and plaster down to the pillars and redid every room. Much luck.
