LOVE IT. worth the price.. for me i started noticing a different within 4 uses over 4 days. if you're teeth are really sensitive i might not recommend it but i am a fan.

They really do work! I used to be a heavy smoker, and had nicotine stains on my front teeth. I used these twice, and they got the stains off my teeth. They also didnt leave my teeth sensitive at all.

Product feels weird on. It feels and looks dirty. Leaving it on for quite a while is also annoying. When finished, I'm not sure that it has done anything at all to be honest. They're expensive especially if I can't even tell that they're working

These strips work!! I'm very happy with the results. They stay put. I can drink water while wearing them if I want to and I don't talk funny while wearing them either.

I've used these whitening strips a few times. They're fast acting and work pretty well. They left my teeth a shade white after using every day for 2 weeks. I only wish it worked faster and wasn't so pricey.

These Crest 3D white luxe professional effects whitening strips are the best! When you drink coffee and red wine, you need these babies lol These work really well, even my dentist has commented on how white my teeth are!

Killed me! This hurt the nerves after using so much. I always read people saying it doesn't hurt their sensitive teeth so I always think it'll work but never does. Don't use if you have have sensitive teeth!

the difference is there!! my teeth were yellowed from all the fast food i eat, so i invested in strips. now my teeth shine and i get compliments on them

This product works wonders! I could tell the difference by the third time I used it. The strips are easy to place and easy to remove. My teeth are super white now. I recommend it, you won't regret having a pearly white smile!

You will absolutely see results pretty much immediately after using the crest white strips. I don't know of any competitor products that do the job quite as well and that are as convenient as the strips.
