Review (3/5): Its ok, not great, not enough power.
I bought because my dog ate another product similar to this one. I kind of like this but a bit disappointed. It stops spinning when apply to much pressure, you need to hold it very gently or very little pressure when I do my heels. My other one was much more powerful. Charge does not hold, I have to use it when plugged up. I wish it was more powerful. Takes forever to get callous off my heels.
