Review (4/5): Powerful Little Tool
This is a pretty powerful tool considering it's so light and easy to handle. It took a little to get used to but it did the job. Some of my callouses required a few more goes at it but it left me smooth once I was finished. The only reason I gave it four stars is because it didn't include the two batteries required which I don't like. These gizmos should always come with batteries so I can use it right out of the box.
