I really like this unit for what it is. The included carry case is very robust too. It is very helpful and I have to say it is good deal. As for its sanding capability, it sands quite fast. Now, this Rockwell sander does all the heavy duty sander.

Rockwell RK4248K Final Thoughts
"Nice little sander."
Spend the money and buy it - you will not regret it. Just be sure you have an air compressor handy! The cord is 6ft, strong and very flexible. Having the 2 inch and 3 inch size is very handy. I was seriously shocked how quiet this machine was.
