Good but Bit Time-Consuming, Combine with Ped Egg for Perfect Results!
Even with the coarsest roller (green), it took longer than expected.  My calluses aren't That bad, but I'm on my feet all day.  Be careful on first using.  It didn't hurt after I finished, but the day after my feet were sore cause I tried to do too much at once!<br /><br />Better to use combo.  Start with Ped Egg (leaves feet a tiny bit rough; same caution, careful not to do too much at once until u know ur feet) & finish with Micro-pedi.  Perfection!
