I have tried regular whitestrips before and I has similar results with the 2 hour kind. I can't use these often because my teeth are sensitive and it made my gums sensitive. But I did notice my teeth were whiter. I just don't think I can go through the sensitivity again because it did bother me...

DOESN'T WHITEN LIKE OTHER TWO-HOUR SYSTEMS
I am disappointed. I left these sticky, uncomfortable things on for two hours (and I HATE HATE HATE wearing these and constantly swallowing little bits of the solution) and my teeth are not whiter! And I can't use them again for three months! No irritation, but no results. Boo. There's over $50...
My teeth are noticeably whiter and they were really easy to use. My teeth feel sensitive, but I know that happens with any whitening product. I definitely would use them again
