Review (5/5): 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.
