Review (5/5): Powerful, rechargeable with no adaptor issue
Works great! The version I received comes with an adaptor that works perfectly well in the US. It's 120 volt. I'm not sure if this is something they changed (based on the other reviews) but there is no adaptor issue.
I like that it's rechargeable and you don't have to waste batteries. The stone is amazingly powerful and cuts through callouses very quickly and effectively.
It's very easy to use. You just flip a switch and it does it's job. It doesn't look or feel cheap and it does a great job.
I received a sample for review.
