Great results, Corded one highly suggested.
This thing works better than any other product i have used. I had very hard heels from day to day walking. I do suggest to get the coarse green ones when ordering if you do have hard hard heels. The stock blue ones work great for mild to light hard heels and day to day use. I do suggest the corded one since no batteries are needed and feels more powerful than the battery one.
