I too, like the man who bought the Revolution, found it to be completely ineffective. I phoned them to let them know(not much interest) and the woman on the phone told me to send it back for a credit. She gave me a post box number. I sent back $90 worth of Revolution, having used the other box to find it completely useless.
That was 4 months ago and never heard back or got a refund. Trying to ring them numerous times, but looks like phone is off the hook. Avoid this company.
