[This review was collected as part of a promotion.] I had more expectations for this product. I like that it is small and compact. This can be carried anywhere. The product is smooth and doesn't have a chalky or slimey texture. The taste is suttle. I was hesitant to use rhis because of sensitivity but I haven't experienced that. I'm just not convinced it has changed the color of my teeth.

[This review was collected as part of a promotion.] This Crest 3D Whitening Kit has 3 pieces-2 steps. There is the 3D whitestrips, which are pretty impressive on their own, paired with a LED light. It fits right over the strips and you use them together. When you finish the strips there is a daily brightening emulsion. You just squeeze it on and go. It prolongs the whitening and prevents future stains. I really saw a difference with this product. That's saying quite a lot. I am old and so are my teeth. While not particularly sensitive, I have had some sensitivity issues in the past with whitening strips. I had a LITTLE sensitivity but nothing to not make the whiter smile I achieved worth it. I did leave the strips and light on just a wee bit less than recommended and still had great results. I don't think I could get my teeth any whiter with an expensive dentist office treatment. The daily serum seems to be really extending the magic. I also drink coffee and tea so this is pretty amazing!!! Would totally recommend.

[This review was collected as part of a promotion.] What initially drew me to this product was the 1 minute apply and go! This product comes with the leave on treatment, whitening wand and a stand. This product states that it's the next breakthrough in teeth whitening because unlike toothpastes and paint on gels which dilute away quickly, it creates a micro thin layer of active peroxide droplets, so thin you cannot feel them. They stay on teeth 10x longer and keep working to remove and prevent drains, prevent teeth whiter with basically no sensitivity. With this product I found clear instructions to squeeze on wand and apply directly across teeth!! I can't wait to see the results of this product over a greater time, but I already see my teeth in a whiter shade!!

[This review was collected as part of a promotion.] I am in love with this Crest Whitening Emulsion on the go kit. It is so easy to use. Great applicator so no mess and easy to get right where you want it. No waiting around for trays! I was surprised that it worked even better than I was hoping! I saw results right away! I'm ditching the trays and switching to this from now on. You can always trust Crest to have top quality products.

[This review was collected as part of a promotion.] I thought this was going to be awesome, but eh. I barely noticed a difference. All that work and all that money for almost nothing. I really wanted these results to be fantastic, I'm so bummed........

[This review was collected as part of a promotion.] This was such as an easy product to use. Just use the wand that comes with the box, squeeze the solution on it and start swiping it on to your teeth and that's it! Literally takes a minute to do it. It's recommended to do it up to 4 times per day for results but I only did it twice a day and I started to notice my teeth getting whiter! Simple to use and works. Love it!

[This review was collected as part of a promotion.] This is the easiest whitening solution I've ever used. There are no mouth guards or trays to deal with. The whitening effectiveness is good but probably not as good as more professional products. That said, it did not make my teeth and mouth feel sensitive.

[This review was collected as part of a promotion.] Very simple to use, seems to work as advertised. Not unpleasant at all to use. For severely stained teeth, you may require multiple applications. The applicator makes this real simple to use with very little mess.

[This review was collected as part of a promotion.] I have used the Crest Whitening Emulsions On the Counter Apply & Go kit multiple times in the past couple of weeks. I was able to see a difference on my teeth after the first use. I am able to apply the Crest Whitening Emulsions On the Counter Apply & Go before I commute to work everyday.
