This product worked really well for me. The pros were that I definitely noticed my teeth getting White, but the only downside is that I have sensitive teeth and I felt my teeth get more sensitive after using this. I would use this product again just without daily use.

I use these white strips just because they're located most convenient. With the price point you can most definitely find something cheaper that works just as well. Also if you leave on to long they make your teeth very sensitive. Crest 3D White Whitestrips 1 Hour Express Teeth Whitening Kit

I was very nervous about buying this. Not only was I skeptical about its ability to remove 14 years of stains but I thought spending money on something ineffective was stupid. It turns out, I was the stupid one for doubting this amazing product! I finally got this product and my teeth are so much whiter now. All the stains from coffee and tea are totally gone. It didn't even hurt my teeth! And my teeth are very sensitive. Please do not waste your money on other teeth whitening products. Free advice-Get this! Coming from a smart shopper, this product is totally worth every penny.

These are really effective whitening strips and you can see really good results after only one use, but when it's actually on my teeth, I get this really achy feeling in my tooth that really hurts. It goes away after taking them off but other than that these are super effective.

I use these once per year for two weeks (don't skip a single day) along with a regular whitening toothpaste when I brush twice per day. Ever since I began using them, I get compliments about how white my teeth are. Every six months at my cleanings, my dentists and without fail they have each commented on how white my teeth are. Never had a professional whitening procedure done in my life. So they DO work. I'm a non-smoker and seldom drink dark teas/coffees.

I've used this product in the past and was very happy with the results. Have you made changes to the product? I'm on my 2nd box and it just doesn't seem to work as well as it did a year ago. At first I could tell a difference; but I don't have the "whitening" I had from the same product a year ago.

I use Crest 3D white luxe glamorous toothpaste and I must say it works wonders. I was using another brand's toothpaste that was alleged to whiten your teeth but instead what it did was create dark lines on my teeth. Once I started noticing the lines I switched to crest 3D white luxe and I noticed it removed the dark lines on my teeth and my teeth were looking whiter. If it weren't for this toothpaste, who knows how my teeth would look, I highly suggest this product!

These are great. I just hate how long they take. And you also can't eat for a certain time after and I feel like the whole time portion of takes up a lot of my day, so my piece of advice is to manage your time better if you want to use these. Overall: 9/10

This stuff really makes my teeth whiter! I've used this a few times and have only had one problem. The one day I had it on for about as long as directed, and I got a shooting pain in one of my teeth. Moral of the story is if you have sensitive teeth, be cautious of how long you wear them for!

I am only 5 days in and I have already noticed an extreme change in color of my teeth. You wear the strips for 1hr a day. The strips are big, so I cut them in half (horizontally) and get double the use out of them. My teeth are usually sensitive and I have not experienced much sensitivity at all throughout the 5 consecutive days I have been doing the treatment.
