What more can I say about this device other than it's a wonderful tool to have in my facial care remedy regimen. There is nothing else out there for the consumer that is better the mess as far as I know. I like the way it feels in my hand it has a great grip. It lasts as long as my session will go. Sometimes I just touch up an area and sometimes I do my entire face. Obviously it's a bit scratchy at first but pain is beauty and vice versa. The videos definitely give you more insight I would recommend watching the videos but overall this thing is easy to use and will change the way you regimen your face therapy routine.
