Bests & Worsts Reviews from Amazon

Update: I have used this about every two weeks for nearly three months...and now it stopped working. After only 3 months! Poorly made product!! Update again: I received a new kit from the company along with a hand written note about how they're trying to fix the issue that I suggested in my previous review. I am VERY impressed with their level of customer service and how they just sent me a new kit without me asking. Great service! I bought this a week ago and couldn't be happier! I love how they figured out how to make my teeth not sensitive for 2 days after I whiten them. I would recommend this product to everyone. I really think this is gonna be a winner!
