A bit under powered but does the job.
Because it says upgraded I was expecting the motor to have more power, but it still did the job with a little more effort. I have to exfoliate my feet regularly and it can be time consuming without great results. Sometimes twice a week. However, after using this once my feet are still soft more than a week later. This will dramatically reduce how much effort I have to put into this process.
