[This review was collected as part of a promotion.] This comes in a nice sleek tube making it easy to transport anywhere. It is simple to use, squeeze the tube, and apply. Once you have applied it to your teeth, you can barely feel it or see it. No need to rinse off. I used this right before work and actually forgot I had it on. After my first use, I had some minor sensitivity in my gums/teeth which I didn't feel for hours after applying. It went away quickly. You can use this product multiple times a day and it just continues working. I'm happy I found this.

[This review was collected as part of a promotion.] I love this stuff!! I use it all the time. I like that you can just smack it on and leave the house. The best way to apply it is on dry teeth. It's a little awkward, but totally worth the results! Doesn't taste bad or leave an icky taste in your mouth.

[This review was collected as part of a promotion.] I always dread whitening my teeth at night with trays and waking up with super sensitive teeth. This in the go option, I felt, was comparable to wearing trays and much quicker and easier! Highly recommend! I could definitely tell a difference after the first couple applications!

[This review was collected as part of a promotion.] I have used this emulsion for awhile, until the tube was gone. I noticed maybe one shade of difference. I am a smoker so that doesn't help. It tastes okay and doesn't cause sensitivity, just isn't very powerful.

[This review was collected as part of a promotion.] I received this product and was a bit skeptical as in the past these types of whiteness have tasted really terrible. To my surprise, this ones tastes as great as it works! The emulsions did not feel like it painted on rather it seemingly glides on, works well and tastes very refreshing. I like how you feel like you like your teeth are just slightly coated and not painted with heavy cream. I would recommend anyone seeking whiter teeth on the go to try this product as I think it's very easy to use and pretty AMAZING!!!

[This review was collected as part of a promotion.] This came in a easy to use bottle. You just put it onto your teeth from the bottle. It was easy to get it onto my teeth. I liked that I did not have to pour it out to use the teeth whitner. I could just squeeze it and move it along my teeth to put it on.

[This review was collected as part of a promotion.] I bought this two weeks ago and I'm starting to see a whiter set of teeth. This is far cheaper and easier then going to a Dentist and having them do it there. Fast and easy, that's just the way I like it.

[This review was collected as part of a promotion.] This Crest Whitening kit works great. Within a week my teeth were several shades whiter without giving me any tooth sensitivity. I will definitely be purchasing this Whitening kit again as well as recommending it to all of my friends and family.

[This review was collected as part of a promotion.] This product is really easy to use! Smaller on the go sizing of the product. It seems to work quite well. We have only used it once so far and can already see the difference! Will definitely be getting more of this!

[This review was collected as part of a promotion.] Crest Whitening Emulsions is perfect and easy for whitening teeth! I have tried a lot of different types of whitening solutions but this one works well and is quick and easy to use. My teeth look much whiter than before I used it. As an every day coffee drinker I need a solution to keep my smile looking fresh!
