Not silliest, but I Just Had. To. Have. It.
The Caruso Molecular Steam Hair Setter. I believed every word of the informercial. When I finally got it in the mail, I instantly opened it and repeatedly burned my fingertips on the "revolutionary" steam action.
The curls never came out like they did on the commercial.
This is a newer version of the infomercial, but the fantastic promises are just as insane!
