Bests & Worsts Reviews from Amazon

I'm very disappointed with this product. I used it for 3 days, and every morning my gumline was burning. In addition the solution was clunky once applied to my teeth. So at night it was ok, but in the morning the thicker remnants took a bit to get off. I can't say it didn't whiten at all as it's hard to tell. I do know I wouldn't get this again
