MINIMAL RESULTS Have ordered Crest Whitestrips from Walmart before with excellent results but these didn’t deliver. I could barely tell any difference in my teeth’s color after using for the full course. Also compared to others I’ve used, these didn’t have the taste of hydrogen peroxide or the slight fizziness of it either which leads me to believe that these were defective. Way too expensive to get no results.

They really whiten 🦷

I have been using these strips for some applications and if I don’t touch they whiten my teeth quite well. They are easy to apply and adhere well, they don’t move much when talking. In my case I have sensitive teeth, so I reduced the time of use and frequency, and I still saw progressive results, without so much pain. The taste is tolerable and not uncomfortable.

Whiter teeth are achievable!

I was skeptical about this product but my dental hygienist suggested it and so I tried it. I am totally happy with the results! It really works. Love my new smile!

Some of them were not sticky which made them useless. I am very careful not to touch e side of my mouth but still they slipped around and did not stay put in place on teeth. Very disappointed. Not sure ifthey were old r just poor quality.

Terrible product , wouldn't stick teeth !!

They may work if they would stick to the teeth , only 1. out of 3 would stick ...so i got frustrated and gave up halfway through after throwing away 2 out of 3 packs ....

Convenience

I'm a school bus driver, and it's very easy for me to put these on.After I drop off my first school because I have ten minutes in between and i put them on before I go get my second school. And by the time I'm done, it's been long enough for me to take them off when I park my bus. So far, i'm happy with the results, and i'm not even done with the process yet.In my teeth already look great
