Happy with the packaging and ease of use. I am not far along enough to see any true results. They certainly have not occurred overnight or immediately. Advice I would give is to make sure your teeth are as dry as possibly before applying - otherwise it does not spread easily or stay on your teeth. This is something I don’t believe was on the packaging and would have been helpful instructions. I feel like I wasted a good bit the first couple applications for this reason. The “mint” taste is decent - certainly better than most whitening gels. There is some of that aftertaste, but not terrible. If I do start seeing results soon, I would give it another star.
