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. 

i've used the white strips since they have existed and my teeth are pearly white. i have such white teeth. i get so many compliments and everyone always asks me what i do. i really should sponsor crest lol

These are super effective but are unnecessarily expensive!! They definitely make your teeth whiter and look good but I can't buy them that often bc of the price

These are super easy and effective. Just remember to not drink anything for the next hour or so for best results. This is a great way to get results without breaking the bank.

These work so well! I was amazed with the result when I first tried them. I saw the difference in 3 days and the result lasts for almost a year which is amazing. I had a lot of people asking me about my teeth. The difference is very noticeable.

Best whitening strips. I see results in one use and I never have sensitivity. They stay on and do not slip. The taste also is not too bad. I always brush my teeth directly afterwards.

I swear by these strips! They are pricey however you cannot beat the results! Just as effective as going to a professional and require less time! Can cause sensitivity, just use them as recommended and no longer

Maybe it's my teeth but these have caused me to have some sensitivity issues while using them. My husband and I both used them and had some sharp pains near our gum line. We bought a whole box and haven't used the rest :(

I've been using these in preparation for my wedding, and they are AMAZING! My teeth have never been so white. I've been getting so many compliments and I always say that this product is the way to go. I would HIGHLY recommend.

I love this brand and buy it for my relatives like a gifts. Very visible results after first applying. Highly recommend, but if you have sensitive gums, consult your gentist before using it or at least make using time shorter.
