Recieved this yesterday in the mail. Used last night. The glory!! No more of the fingernails! No more gouging, no more gross bacteria, no more inaccessible impossible black heads. Sure, there are still the tough ones that you have to let come to the surface first, but once they have you can clean them up with no fuss and little flare-up.
I'm going to buy this for any teenager I know. I wish I'd had this 10 years ago.
