I love this sander. The only thing I didn't like is that the dust collector doesn't have an unlocking mechanism. You have to force it off, making it inconvenient if you store it with the collector off. I ended up returning it because there aren't enough tools in that 20v range that would cost a lot for the home dyer. The manufacturer also sells other lines of brushless tools under other brand names. I have found a more complete line at an affordable price among other manufacturer brands.
