Review (5/5): Handy, effective tool, but can't use when plugged in
I had to get my feet beach ready over night and got this tool. My heels get really calloused from all that "barefoot" training/running stuff. I bought the coarse rollers and used that first. It's messy- take it outdoors or in the bath. If you have borderline OCD like me, reign that madness in, otherwise you're going to take off too much and your feet will be tender. Do over a few days and still use a good moisturizer on your heels. Wash off the rollers to keep them effective.
The only thing that bummed me out about this tool is that if it's not charged, you can't just plug it in and use it. Also, I charged it for what seemed like forever and the indicator light never told me it was done, but it was still pretty effective after a first charge of the recommended time.
