[This review was collected as part of a promotion.] This is great for use when your busy and on the go. Small compact size fits in any purse or small bag. Easy to use and works great! Quickly able to apply and go on with my day. Definitely will be recommending to others.

[This review was collected as part of a promotion.] I really like this Crest Whitening Emulsions Treatment. I like that it is easy to use and it is very convenient because you just apply and go! You have more control with this because you choose what teeth you want whitened. It says you can use up to four times per day, but I only used it once per day and I noticed that my teeth were whiter!

[This review was collected as part of a promotion.] I have been using crest 3-D whitening strips for a long time and used to get great results with them but as expected they take quite a while so I would have to use them for at least two weeks before I noticed noticeable differences. They're also a little bit harder to keep on your teeth sometimes it would slide off or they wouldn't be on really well. Compared to the 3-D whitening strips the emulsion whitening is so much easier to apply. I started seeing noticeable results within four days. It could vary depending on how much and whitening is required though. No intense cleanup is required and I am able to do my normal day-to-day activities while I have this on.

[This review was collected as part of a promotion.] I have used the 1 hour express for my top teeth only and it works amazing after completing the 7 days of strips. Well worth the $. I saved the strip that is supposed to be used on the bottom teeth and used them for another 7 days on my top teeth and saw an even better level of bright white.

[This review was collected as part of a promotion.] I love that I can whiten my teeth while driving. This is perfect for my ever so busy schedule. The taste isn't awful and it's still too early to tell how well this item works. But anything is better then nothing.

[This review was collected as part of a promotion.] Crest Whitening Emulsions on the go is so very simple to use. I love it. Just squeeze and apply. Can be used anywhere. Most whitening products are very sensitive on my teeth, this is not! No sensitivity at all. It actually works the first time. I noticed it immediately. Great product.

[This review was collected as part of a promotion.] Works as described, made teeth whiter, each item easy to use, no terrible long lasting after taste. Directions are easy to follow. Everything in one box makes it even better. Would recommend to family and friends.

[This review was collected as part of a promotion.] I was worried this would be sticky or leave a bad taste in my mouth but it didn't. I couldn't even really tell it was there. Noticable difference after just a few uses. I've never loved my smile more than I do now. Can't wait to see the results after a few weeks.

[This review was collected as part of a promotion.] I love the concept of this whitener because I dislike wearing the strips and holding the devices. Most times I will buy whitener kits and not use them due to the extra work required. I like that you can't just paint this on your teeth however I'm not sure if I'm seeing a ton of results. I will continue to use since it's easy to use so hopefully that will bring on more visible results.

[This review was collected as part of a promotion.] This Crest Whitening Emulsions product is simple and effective! It's super easy to apply and I don't have any sensitivity when using it. I prefer to put it on after brushing my teeth in the morning and at night but it can be applied liberally throughout the day. It has a somewhat cool peppermint taste that goes away in less than a minute after application and I don't feel or see it on the surface of my teeth. I noticed a subtle whitening of my teeth after several uses. Highly recommended!
