I was apprehensive about this purchase for fear that the power is not high enough! the device is convenient to use, efficient, and full of accessories. often with the underside of my big toe dry and raspy hard hard to put tights without yarn. it's an old story, every 3 weeks I myself my pedicure, I end with a layer of moisturizer and voila. I would have put 5 stars if the device's wireless was not so short. but hey I sit lending my grip and I'm fine. please it is great!
