These are very effective and i see results after about a week. They do make my teeth a little sensitive, but it goes away after a couple days. My teeth stay white for several months.

These are the literal best. I apply them a couple days a week for 3 weeks and then take a break. I get compliments on my teeth and their whiteness. They fs are effective.

i’m not entirely sure if they work- but they definitely do give me a bit of sensitivity both on my teeth and the gums around my teeth that the strip touches

[This review was collected as part of a promotion.] These whitening strips work really well!! It’s very comfortable on the teeth!! It doesn’t hurt my teeth at all!! I love the packaging!! The value is very good!!

These whitening strips make my teeth shining white! I use one box, take a break, and then use them accordingly. They don’t affect the sensitivity of my teeth at all. I would recommend these strips for anyone looking for whiter teeth!

Overall this product is okay. However it is very irritating to my teeth. It causes very bad sensitivity which is something I do not usually struggle with. I won’t buy it again however it is pretty inexpensive and does show results.

This product is very effective. But be careful... don’t overuse! I made that mistake and my teeth became overly sensitive and my gums were very irritated. My teeth become noticeably whiter once completed.

Like to use these occasionally because it works after awhile and doesn’t irritate my gums. The only downside is it sometimes irritates my throat if I do it more than twice a week

These Whitestrips work, however they have made my teeth extremely sensitive. If “beauty is pain” is your thing then go for it but the discomfort I encountered isn’t worth it for me.

Really good. Just finished 5 days. It really whitens significantly every day. It was a great purchase and I like that it is 20 days then 1x a month to maintain for a year.
