Negative Positive
Title: Few weeks for nothing!! It did nothing!
Review: I used this with a tray 2 x a day 10 min a day each time. NO RESULTS. Will stick with the BriteWhite pen or whatever you call it that seems to at least get some results. I know my teeth are moderately stained, not extremely. Went by the positive reviews. I just drink coffee, not smoke. The positive reviews failed me this time!
Is the review positive or negative?
