Review (5/5): Very good product and very easy to learn
More power than a battery one but it will bog down if you press hard. No need to press hard though. It whizzes through the callus skin.It actually will burn you if you stay in one spot too long. Very good product and very easy to learn. Just keep it moving. Love it. The refills are only about $7.00 too. I need a face mask because even with a little callus, a cloud of dead skin comes up so be prepared for that. I don't know how long it will last because I just got it but so far it's great.
