Compact and did the job
This product did the job. It is compact and easy to use.  It has different filers depending on how hard the callus is.  I used it on my big toe and heel. That is where it needed the most work. I used the lighter sander to do my heel and rougher sander on my big toe.  It did not have labels as to which one was which so I had to look closely at the sander to see which one I needed to use.  What I didn't like about the product is that there is not catcher for the dead skin.  It left some on the sander and I guess the rest flying everywhere at first.  That's when I realized I should do it in in the shower, over the bath, or put a trash can underneath in hopes that that is where the dead skin end up at.
