Query: Don't be stupid like me and buy this piece of junk

WOW! I must really be desperate to buy something like this. The premise behind this electronic piece of garbage is that it "calms the savage beast" with it's soothing ultrasonic music. Kind of like that Bugs Bunny cartoon in which Bugs hypnotizes a crazed gorilla with a violin. I have no way of knowing if this thing actually produces a ultrasonic tone, it might just be a empty shell, it has the same effect. Nothing. Nadda. Zero.
