Many love this product and while it does work and do it's purpose and effect I've had some negative experience with gum burning and stinging and cannot let it last the duration.

I like these Whitestrips from Crest! It does what it promises and I don't think my teeth get overly sensitive afterwards. I wouldn't use it for consecutive days though. I would definitely buy it again.

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 use these strips with my teeth whitening light and notice such a difference. This formula doesn't “foam” like other brands and stocks to my teeth well

First time using product and was pleasantly surprised. I did see a difference of whiter teeth after using several strips. I also did not experience much teeth sensitivity, which I was worried about. I plan to use another set soon!

These strips work well whitening my teeth but I do feel some tingling near the gum line towards the end of the directed period to leave them on. Once applied the strips aren't too bothersome but they can be a bit bulky and awkward to apply.

My husband and I really wanted to whiten our smiles! We have noticed there are some strips that grip your teeth better than others. These were great! We noticed a difference in a week!

Does what it says it will do. After a few days my teeth were already whiter, my mouth felt cleaner, and I smiled more. Would recommend Crest 3D White Luxe Professional Effects Whitestrips Teeth Whitening Kit

I use another version of teeth whitening from Crest for normal use. When I need an extra boost I use these. They seem to be stronger and work faster. Great product.

I was skeptical if these would work or not, but they do. If you keep using them you will see results. Takes a while but it does work. I've tried other strips just to compare but it gets a bit messy. These ones don't have that problem.
