[This review was collected as part of a promotion.] This product was super easy and effective!! After just one use, I could already notice a difference. You put the gel on, await the requested time frame and then use the whitening unit for like 3 minutes! It is a little annoying, but the ends definitely justify the means!

[This review was collected as part of a promotion.] The Crest Whitening Emulsions leaves a lot to be desired as far as a whitening product goes. It's messy and hard to apply with the applicator that is included. The product does not stay on well either. The whitening light works well.

[This review was collected as part of a promotion.] I love this crest whitening set. The crest emulsions is great on its own, but this set with the light is amazing! I can see instant results right after doing the light with the emulsion gel on my teeth. I use it morning and night and I am well on my way to having white shiny teeth.

[This review was collected as part of a promotion.] I bought this set up about a month ago and holy cow am I glad I did. Very easy to understand and set up, you put this application in your mouth and it seriously whitens your teeth. I have got everyone in my family one of these set ups and they absolutely love them.

[This review was collected as part of a promotion.] Crest WHT EMUL Light works great! I have to admit i was skeptical at first. But it really works. The directions were easy to follow. It was easy to use. I will absolutely be recommending to all my friends and family.

[This review was collected as part of a promotion.] I really like this whiting kit. It has a great mint taste which make the time you have it on easier to handle. The light is a nice extra touch that i did see a difference when you use it. I like that I can use it more than once a day as well.

[This review was collected as part of a promotion.] This teeth whitening system is so easy to use. I am amazed at how it really does not hurt or cause sensitivity. I've used whiteners before that hurt! I have noticed subtle changes as I use it and that is good, I don't feel like it overwhitened too quickly, but works slow and steady

[This review was collected as part of a promotion.] I used this for about a month and it is by far one of the best at home whitening kits available. The led light on this gives an extra boost to help the whitening process. It was easy to use. And after 3 minutes of use it gives you whiter teeth. Beats paying hundreds of dollars at the dentist when you get the same whitening effect for way less with this product

[This review was collected as part of a promotion.] Great way whitening your teeth. Easy to use and great product all together. Each day my teeth get lighter and lighter. Aboustly great product all together. And great way take care of your teeth between dentist appointments.

[This review was collected as part of a promotion.] I received this product to try and have been using it for 2 weeks now. I like that the taste of it is not nasty. I also appreciate the simplicity of usage. This whitening product does not make my teeth sensitive, even if I decide to use it multiple times a day. Although I like also of those features, I don't think this Crest whitening emulation product is whitening as promised. After 2 weeks, I've only seen very minimal results.
