Review (5/5): Very Satisfied!
I had purchased another brand of this type of unit (nearly identical) that runs on batteries. It was a waste of money. The reviews on this unit indicated it was much more powerful and did not bog down as you pressed it into a callous. The reviews were correct! This unit is very nice and has plenty of power. Like the othe reviews suggested, I picked up an extra 4-pak of the heaver grit sandpaper rolls and they work just great!
