the top head removes easily to exchange to other file head
Comes with 2 heads in the package.  Requires 2 AA batteries, the top head removes easily to exchange to other file head, provided with this package.  Easy to use, it does slow down if you push a little too firm, which is a good thing.  It works great on my heels, smoothing them down.  I hope they sell replacement heads soon.  I'd highly recommend this.
