[This review was collected as part of a promotion.] It is easy to apply and does not taste bad at all. Much easier than strips that I had previously used and much less time consuming as well. The applicator works really well and cleanup is also very easy. I have been using for a few days and am already noticing visible differences.

[This review was collected as part of a promotion.] This product is super easy to put on. And I was doubtful that it would work. But after only about 3 days my teeth are definitely whiter. It does not taste bad like my experience with other whiteners. It's a light mint taste. Definitely worth a try. Just squeeze, put on your teeth and go!

[This review was collected as part of a promotion.] I have been using these crush strips for about 3 weeks now and I can tell a huge difference in my teeth. They are so easy to use just stick the strips on and go about your business for the next 10 minutes. You take them off you're good to go and make sure you do the comparison so you definitely can see that difference because it's amazing to see how good the product has worked in a 3 week period. I highly recommend this product.

[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.] This is simple to apply straight out of the tube, and I have not had anything displeasing about use in terms of taste or sensitivity on teeth. Have only been using for 1 week, and have not seen any striking changes in terms of whitening, but imagine this may improve with continued use. Could use a bit better instructions in terms of how much product to apply - the first few times I think I way over did it, so the tube probably won't last as long as intended.

[This review was collected as part of a promotion.] Saw a difference in one week. My teeth are so much whiter! I drink a lot of coffee and it showed on my teeth. My teeth are very sensitive so I was worried about using this since I can't use whitening toothpaste without pain. I had sensitivity one morning when I woke up but it's completely gone now and hasn't returned. I have been putting it on every night before bed and in the morning before work. Also, love how it doesn't have that awful peroxide taste..

[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 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.] I started on my Crest whitening emulsions and I must say that I have the best white teeth ever. I love that it goes on easy and it made my smile instant WHITE. I highly suggest it for immediate results. You hold it like a pen and brush it on. It is super easy.

[This review was collected as part of a promotion.] worked great! I am so pleased with how the crest whitening emulsions work and how my mouth feels so fresh after applying them. I don't have to worry about keeping a strip on my teeth for an hour or having a goopy film on my teeth! My mouth felt great for half the day. I have sensitive teeth to begin with and always worried about whitening products bothering my teeth; not with the emulsions. I am definitely pleased! Great price and I can carry it with me wherever I go.
