Review (5/5): Love this little device!  It's a multi-tasker!
Best invention ever! Almost. This little thing not only files off some pretty hard callouses, but also does a FANTASTIC job on toenails! I loved it so much that I've given one to my mom, my dad, and my spouse and they are all raving at how easy this is to use. Great gift for anyone (especially seniors) experiencing foot problems that need help getting to their toenails. Delivery was very fast and nicely packaged.
