Fine but I don't get why it's so pricey. Also it's gross that it kind of dissolves in your mouth.

I didn't see much difference at all. Very expensive for no results. I wouldn't buy again.

Easy to use and good results. The crest 3-D white strips or a good quality product at a good price.

Im used before Amazing ,perfect and very comfortable

Used the whole box, and barley changed the color of my teeth. Not worth the price or the buy.

Really liked this product, was easy to use and great results.

These leave your teeth sensitive, but do their job. They are super expensive though.

This box of strips for the price is not worth it. Very disappointed.

This product is quick working, good results and cost effective.

Noticeably white after just a couple of days! For the results the price is very reasonable.
