I bought this sander as a replacement for the same model that I purchased about 30 years ago. The old one still works after constant use making furniture, toys and other projects. Most of my work now is making toys and puzzles for Grandchildren and craft fairs so it gets quite a bit of use. The best features of the tool are that it DOES take a 1/4 sheet of sandpaper. It is comfortable to use for prolonged periods of time. It can be used to round sharp edges and get into difficult spots as well as the normal flat surfaces. The true orbit speed leaves a satin smooth surface without swirl marks on soft or hard wood. The old sander is now vibrating more than it should so I plan on having it reconditioned and the rubber posts replaced. I'll be happy to keep the old friend as a spare! I would definite advise anyone looking to purchase a finishing sander to look no further than the Speed-Bloc You won't be disappointed.
