Review (4/5): Not so tasty--but my teeth are whiter!
I've been able to use this for a few days now. If you're able to get past the awful taste, and are patient, results will start to show. I'm always wary of things that make promises that seem impossible, but after slowly seeing results I'm better able to get past the taste. Definitely recommend this product if you're looking for something that's cheaper than they crazy-expensive whitestrips!
