Have bought the Pedi in retail and was pleasantly surprised after the first application. After the bad reviews I was skeptical at first because I'm pregnant and so sometime soon no longer so well come to my feet with the cornea file or rasp, I have decided to buy. Did not regret it, surely does not immediately everything cornea in the first application from, but still had the same a much softer feel on your feet. The application looks really simple, does not tickle and by the automatic speed regulation at excessive pressure, the risk of injury is really low. It occurs to me that many have here apparently disregards the instructions, and so excited about stopping the role. One should not operate power press hard, but let it glide smoothly over the cornea, in my opinion, pressure is not necessary, with regular use you get the cornea down well. For me, definitely not a bad buy and highly recommended. A star's deduction for the price, the unit is now really cheap not.
