I already have a hand sander but was frustrated with having to fold and break/cut the sandpaper to required size and then use a tedious clamping system, to secure them. The hook and loop system on this grinder is amazing. I can sand it down and everything stays in place, and it's not difficult to replace the gasket when it wears out. Also the vibration adjustment switch is very useful depending on what kind of work I'm doing with it. I was very impressed with the number of sanding pads that came with the kit as well as the car polishing pad. The dust collection hole works fine, just be sure to line up the holes on the sanding pad with the sander for this to work. Would definitely recommend this grinder and even compare it to more expensive well known brands.
