Review (4/5): Effective but no replacement rollers available
This really is a throw away device. I bought the Amope' and Scholl replacement rolls but they are about 1/8" too long to fit so save your money on replacement rolls. I have hunted in stores and online without luck. However, given the price of replacement rolls for Amope' and Scholl callous removers, the Calily isn't actually a terrible price given the included rollers are very durable. It is quick to charge and the length of time for use till recharge is really quite a long time. If there were replacement rollers available, this would be a 5-star nice, inexpensive callous remover. Without available replacement rollers, it is a reasonably priced disposable callous remover that is very effective.
