[This review was collected as part of a promotion.] I have finally found an at-home teeth whitening system that works. At first, I was intimidated to use the LED accelerator light but once I gave it a try it was so easy to use. I noticed whiter teeth after the first use. The best part is that I didn't feel any sensitivity in my teeth. I'm looking forward to using this product more.

[This review was collected as part of a promotion.] Wow, I’m amazed by the results I received from the crest teeth whitening and light. I’m beyond thrilled with the results. It’s very simple to use and just after the first use you see results. I used this for a week and my teeth have been the whitest they have ever been. I’m in love with this product. It’s a lot easier than the strips.

[This review was collected as part of a promotion.] I like this product. It is easy to use, easy application. Results can be seen almost immediately. My teeth were a few shades lighter and can be visibly seen. Definitely would recommend to family and friends.

[This review was collected as part of a promotion.] I have always wanted whiter teeth. For about 30 years, I smoked cigarettes (I quit 3 yrs ago). While my teeth were never yellow, they just weren't as white as I wanted even though I tried other products that promised to whiten my teeth. This Crest system is so easy to use and doesn't take up too much of your time. The gel is such a pleasant minty taste. I like that you can use this multiple times a day. While my teeth are not as white as the commercial, I can tell they are whitening!

[This review was collected as part of a promotion.] This stuff is sooooooo amazing!!!! The crest whitening emulsion LED light has worked so well I see results in just a couple days of having it . I definitely recommend it with all hands up!!!! And by the way it is so easy to use.

[This review was collected as part of a promotion.] Always kind of sceptical about teeth whitening products. This one I must say is by far my favorite. Very easy to use. Read directions fully before using. When using for the first time you will see a little difference,but after 2nd and 3rd you really start to see. Great product!

[This review was collected as part of a promotion.] I was skeptical to try it out as my teeth tend to be sensitive. I've done 3 applications so far and no sensitivity whatsoever and I saw the difference after first use. The only thing I don't like is the taste. If they could change that it would be a total hit.

[This review was collected as part of a promotion.] I tried out the Crest - Crest WHITENING EMULSIONS Light 18g/21mL 3ct and it works great! I love that it doesn't have a plug in. It does make it a little heavier, but not by much. It whitens very well. It's so easy to use. You turn it on and when the times up a red light turns on. No timer needed. I highly recommend trying this one over others, and would definitely buy it again.

[This review was collected as part of a promotion.] I did use this whitening emulsion kit a few times a week, and saw little to no change. The directions have you apply a serum to your teeth, and then wait 30 minutes before using the LED light for 3 minutes or so until it shuts off. It recommends it up to 4 times a day I believe. But after using, you cannot eat or drink for an hour. Personally I didn't have time to use it multiple times a day and settled for once a day before bed. I didn't see much of a change at all, and I already don't drink coffee or soda. Unfortunately, there was not enough of a change to warrant purchasing again for me. I do use crest's other products, and enjoy them though

[This review was collected as part of a promotion.] I recieved this product to try out , actually I let my granddaughter try it out and she said it was easy to use it made her teeth a little whiter, which is better than having her go to the dentist to get it done
