Title: Best on the market for whitening
Review: I've been using the Night Effects since I first tried it a year ago. My teeth look like I had professional whiting done. I just have to touch up for a couple nights every once in a while. As long as I replace the cap as soon as I get my teeth covered it doesn't dry out to the point it's not usable (although I did like the packets better than the canister because they didn't dry out and the amount was about right). I dry my top then bottom teeth, then paint the bottom and then the top. Once you get practice it's quick and easy. I keep a big grin on my face for a couple minutes for it to dry. In the morning I wipe the majority off with a tissue. I don't like any of the other strips or trays. Best of all are the compliments!
