Review on Rockford Ergonomic Sanding Sandpaper Reducing by Miro Dadee

The grinder works very well. Great price as it comes with a nice set of grinding wheels. I've only used it on soft wood, but it's much better than a piece of sandpaper on 2x4. Sandpaper holds up very well, is easy to hold and surprisingly sandpaper doesn't scratch your thumb or pinky/ring finger. These fingers are pressed against the sandpaper to get a good grip, but they don't scratch at all. The only downside is that the curved design makes cornering difficult.
