Stop! RIP OFFS Don't fall for the trial offer gimmic. Its a rip-off they advertise for a free trial, was suppose to be a promotion. NOT! Took ten days to arrive and not able to cancel on line .The product made my teeth hurt, making them very sensitive to hot and cold.That turns into a charge of 78.23 charge on your bank account. The reps didn't want to honor you with a cancellation or refund. BEWARE of that Free Trial offer...It'll cost you. read full review »
