Title: Disappointed
Review: The gel in the trays does not stay in place. Within 5 minutes of having them in my mouth the gel had slipped out and was dripping everywhere. The bottom tray was especially bad. Not sure how well they whiten because they don't stay in place long enough to do any good. I would not recommend using these.
