WHAT A SCAM!! Doesn't work worth a darn. Also they expect you to put this on TWICE A DAY and not close your mouth and walk around 'smiling' like a jack@$$ for 15 minutes at a time. They billed my credit card $39.95 AFTER I cancelled and they basically told me 'too bad'. I was only able to get part of that back (well, not yet--we'll see) but they seem to take pride in ripping you off! There's no free trial. They still end up getting more than $25.00 of your money. DON'T FALL for it!!! read full review »
