It's supposed to do a helluva lot more than it actually does. If you read what is written on it, especially from Asia, it sounds lke magic. It will give you a permanent erection, cure cancer, wash your car, teach you to play the violin.....Don't spend money on it.
Shit I always wanted to learn the violin!!!!!!!!! Well there goes my dream of playing the Phil-harmonic orchestra.....My life has no meaning now!
