Review title is First run went great! [SEP] I plugged it in this morning and just now (about four hours later) I gave it a test run.<br />It kicked the butt out of my especially bad heel, I had such a large callus with a crack that it hurt to walk around (sometimes hurt while just sitting...) and it did it within a few minutes.<br />Normally I sit on the edge of the tub with my feet in there so I can rinse away the dead skin but I did this heel on my floor so I could get an “all this in a few minutes” picture for the review.<br />I just bought it so I’m not sure of downsides of faults yet really.<br />My one complaint (so far) is that you have to be somewhat strategic with how you hold it because the case back comes up kind of high on the roller, vs the one they have where you can access more of the roller.
