These whitening stripes make my teeth sensitive. I don't think they even work that well. You'd probably have better luck using a whitening toothpaste. I don't think they are worth the price and they definitely aren't worth making your teeth hurt.

If you're looking for a good whitening kit well this is the brand for you ! It whitens in a matter of minutes ! It lasts a long time too ! I've tried other brands but none worked like this one . I recommend everyone to purchase !

Love this whitening product it makes your teeth look very pearly white I love the fresh sand that this white strip leaves doesn't leave the teeth feeling very weak leaves and feeling very strong and healthy which I love

After consistent use, you will definitely tell a difference! A single use won't get you the results you're looking for though. I use these for 1-2 weeks about once a month or every other to keep my smile white enough.

These things are awesome! Made my teeth look amazing. And one other great thing is their staying power. They stick so well to my teeth I never have to worry about losing one too soon.

These are the best teeth whitening strips! The work so well and do not leave my teeth feeling achey or sensitive after using them. That is so important to me when using a white strip. I will continue to use these for a brighter, whiter smile!

They are okay but don't seem to whiten as much as they used too. They also make my teeth very sensitive very quickly compared to other whitening products. I don't think I will be using again. I recommend if you haven't used strips in the past.

I have a love hate relationship with these. I think when used consistently they can work, but they NEVER stay put which I feel can hinder the working power.

Great products ! Dis an amazing job leaving my teeth sparkling white ! It however did cause sensitivity but I've never used a teeth whitener that did not.

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!
