[This review was collected as part of a promotion.] I started using this product 2 weeks ago and I can tell the difference but I wasn't really impressed until my wife actually tried she got awesome results and made me a believer. This product is safe because it didn't made my teeth more sensitive as other product with the same purpose did.

[This review was collected as part of a promotion.] This is a quick and easy way to whiten your teeth. There's times I just haven't had ir taken time to whiten my teeth and need a quick fix. The Crest Whitening Emulsions in the go works! It's a great temporary fix when you need a quick whitening. And it boosts your confidence knowing your smile is up to par.

[This review was collected as part of a promotion.] Easy enough to use, and a noticeable difference in color when you compare before and after pics, but I didn't notice as much without the pics. Definitely take before and after pics, otherwise the changes may be too subtle to notice. Would use again, although not yet sure if this works better with the light or if the strips by themselves produce the same results.

[This review was collected as part of a promotion.] I have tried many tooth whitening pastes and I really like the results from the Crest Whitening Emulsions. It is very easy to use with simple directions. No overpowering taste and no icky residue is all also a plus!

[This review was collected as part of a promotion.] My teeth have been needing a whitening for a long time, but I'm a very busy person. I'm so glad I found this product! This is so easy and quick to apply, and I don't have to do anything else! Thank you so much for a great product!

[This review was collected as part of a promotion.] Not only does this work great, it tastes good too. I was shocked at not only how great my teeth whitened, but I noticed a significant difference after Only using it a couple of times. The instructions were very clear and easy to understand. It did include A applicator but it also said I could use my finger. Since I am the only one that will use it I did use my clean finger. I keep it in my purse so I can use after coffee with friends.

[This review was collected as part of a promotion.] Crest Whitening Emulsions On the Go makes whitening teeth on the go easy! The applicator for this whitening system is kind of like a lip gloss applicator. It definitely isn't the most efficient at getting a good even layer, paint brush type systems are what I find the easiest and most efficient. But, what's nice about this is that you can put it on your teeth and go! No waiting around for a timer to go off to rinse your teeth. You will want to put on just a thin layer, if you end up with thicker areas I had little chunks of dried whitening stuff in between my teeth that needed to be flossed out. After just a couple of uses I noticed my teeth looking whiter and brighter!

[This review was collected as part of a promotion.] While this is easy to apply and doesn't have a horrible taste, I haven't really noticed a difference since using it. The formula is thick and goes on smoothly but I find it ends up on my lips a lot, making it feel like I have chapstick on. I finish out this tube and see how it goes but so far I'm underwhelmed.

[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 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........
