No need to spend tons of money pedicure, I returned to the beautician / pedicure for moments "pleasure" (which takes care of me), and not to try to make my feet sweeter . This small device is almost perfect: given the "dust feet" when he made the first use, you can say it is powerful and effective. The roller turns with incredible simplicity (there is an eject button, you reclipe another and go again), and cleaning is so damn simple. Two different rolls, which is still positive: a soft and a harder (to buy surcharge). I will only have a few negatives: small plastic flap behind the roller (it prevents easy reach certain areas of the foot, but you can still get by), the rolls that wear out quickly if has much work to do on the feet (over time if used regularly, the rollers last longer because there is less to grate on the foot each time), the batteries which in my opinion will not be short-lived, especially at the rate I use it, I think investing in rechargeable batteries! 4 stars for this little wonder, therefore, that is certainly the Scholl makes 2 times its price (which refills cost a arm). HOWEVER ATTENTION: for those who are attached to this stuff, it is NOT the Silk'n brand, which does not even have that kind of apparatus for pedicure (just go on their site for noticing). This does not prevent its effectiveness, as explained above.
