Review (5/5): I am so happy I purchased this...
What a great idea! I just used my RSB Central Battery Callus Remover this morning and was delighted with the results. I did it outside in the backyard so I didn't have any mess to deal with. It really works well at smoothing out the bottom of the foot. I love it! Then I put it into my shower so next time I use it will be on wet feet, like they do in the salons. Totally easy and simple to use. So glad I purchased this and at such a great price!
