You need to check this one out...
For $60 they will send tones via a phone, any phone, and it will improve your sound!!!!
They also make a clock, pebbles, and numerous other things that apparently get sold... I want to get into something like the teleportation tweak. Even if only a few hundred people buy it, it's literally FREE money! Make some noise and collect the cash.... I really am in the wrong field!
