[This review was collected as part of a promotion.] It seemed to work well although i have only used it once so far. i love the idea of it it seems very covenient vs the strips but idk. I like it we will see how much it does!

[This review was collected as part of a promotion.] I didn’t know I was getting the extra laser light with the teeth whitening stick! I have used them and they didn’t cause any sensitivity and works really well!

[This review was collected as part of a promotion.] Every time I try to use whitening product I stoped at the 3rd day because of sensitivity, well let me tell you, not this time!!! I am very excited and didn’t write this review until day 5 of treatment. I can see a little difference but hey I’m in day 5. The favor is not the best but is not horrible. The packaging was perfect.

[This review was collected as part of a promotion.] COMPLIMENTS OF INFLUENSTER: I am sampling Crest 3DW pen. I’ve only been able to use it twice so I’m not sure how accurate my review can be, but I do feel like my teeth turned a little whiter in my problem areas. I like using the pen to apply the whitener because it’s more precise. The light helps see the problem areas better. I felt like a professional using this pen. I didn’t care for the flavoring. It tastes like medicine. But for the results you get this is a great inexpensive product for your teeth.

I didn’t get the results I expected but still using.

[This review was collected as part of a promotion.] I think this is soooooo much better than whitening strips. You just paint this on really quick, follow the protocol and then do a few minutes with the LED light! Super easy. I'd recommend this product.

Not worth anything!

I have seen zero change

Concerning you cannot find the % of the hydrogen peroxide that's in this. Only states it's in there for ingredients

[This review was collected as part of a promotion.] I have been testing this product and I have realized that it works! It whitens my teeth gradually and I already see the results, and also its flavor is not as strong as other products I have used before
