Pretty expensive and you have to use them every day but these work so well! My husband and I used them before our wedding and our teeth were very white! Wouldn't use them too often but if I have an event coming up I will definitely buy again

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.

Great for on the go teeth whitening. I've been using this for years and it gives you pearly white teeth without the need of professional whitening. Might feel sensitive at first use but your teeth will get used to it.

These are one of the first white strips i've noticed a huge difference with! They aren't the best for sensitive teeth so maybe don't leave them on as long if that's a problem for you!

This product does work but made my teeth extremely sensitive while using. While using them for the time directed I was getting sharp pains in my teeth that lasted even after removing the strips. I stopped using this product due to sensitivity.

In between my professional teeth whitenings at the dentist, I'll use these white strips for a little refresh. They work incredibly well and are extremely easy to use. I would recommend to others and continue to use personally.

I bought a box of these and could only use one and had to take it off early. I typically do not have sensitive teeth but these were painful to use and sent shooting pains into my nerves! I haven't been brave enough to try a second time.

the best white strips out there! i absolutely love these and how white my teeth look! they're only a little sensitive but it's worth it! the sensitivity goes away.

this definitely worked and my teeth were super white. the reason i gave it only three starts is because it made my teeth really sensitive after and i don't think it's safe for your enamel.

Love using white strips in general I bought this hoping it would help but I'm unsure as to if it really does anything. It's pricey and my teeth never changed color
