“It worked great when it worked! Battery life is terrible and after 6 months it broke. The warranty isn't worth sending sending back. I'm highly disappointed.”

“Good concept but no place to store the mouth piece. Great for a keychain but is someone going to carry the mouth piece separate or search for one.
