I was very excited to try this product because I suffer from red wine teeth (and lips!). There is a "mirror" on the packaging which is hardly reflective. The packaging looks like china town knock off Anna Sui. Worse, I have cotton mouth from the product going on 12 hours and counting. This is the second time I have used this product repeating the same disappointing experience. I wish I could return them. They also make my teeth feel sensitive.
