I used it several times and I am satisfied. However, careful not to use too long, I did the first 2 times. It created a sort of mini trauma. If we do not realize it instantly but after yes. Sas probably pressed too hard and too long, so handle gently. The pedicure also recommended me not more than once a week. Otherwise good grip, light, easy to take anywhere, and great price. A recommendation for regular maintenance before the formation of large calluses on which it will be ineffective.
