These lightning strips whiten my teeth two times l whiter than what they are. They look like I've gotten them professionally bleached. Are use them once a week and have been so happy with my results. 

Price is a high and it leaves your teeth kind of sticky after I usually like to brush my teeth after using these and before . I don't see a huge difference after using I think for the price it should work better

I have tried many at home teeth whitening remedies. This by far has been the easiest to use and the most effective. Twice a year I will buy a pack and use them to keep a nice white smile all year. Love them

These white strips are the very best. I used them before my wedding and people actually complimented me on how white my teeth were and I hadn't told anyone about the white strips. So, yeah they do work, and they work great!!

I love using this! It's easy to apply so you don't have to make a mess using those gels. And you don't have to have a bright light shining in your mouth either.

love these! get my teeth really white within a few uses! not that expensive but not something i use all the time! when used these after awhile, i will get sharp pains in my gums which turns me away from these but they do work!

These don't stay on my teeth very well. It does a good job at whitening but always leaves part of my teeth not as white since they slide around during the application.

These work really well and results are noticed right away after one use. They make it quick and easy to whiten teeth before events and to just maintain the whiteness

Once I got my braces off I immediately purchased these. They are amazing and the only whitening kit I will use. I saw results within days of using and I will definitely repurchase and recommend to all.

I've used many boxes of different versions of Crest white strips. These really do work. My only complaint would be that they make your teeth sensitive. Which I guess comes with the territory. Definitely see results in the first or second use.
