I personally did not get the results I was hoping for but it could also be user error. I got frustrated with the product trying to apply the strips. I may try again in the future but for now I will just stick with whitening toothpaste.

I have sensitive teeth so I do not like using this product often because I feel like it first my teeth after repeated use. But if I have a night out and I need to whiten my teeth quickly this is what I use!

They really work!!! The price is very affordable compared to professional teeth whitening, and you can see results in as quick as 3 days. I will definitely be buying these again and highly recommend them to anyone looking to brighten their smile

I used it for prom 2011 when I was a junior and it made my teeth really white. A lot of people notice. You don't need to spend a lot of money going to the dentist when you can just buy these

I smoke, drink tea and coffee, couldn't ask for a better product. Work's great on my teeth. Crest 3D whitening is what I will use as long as I have teeth:-)

I mean, I'm sure that it works great for people with normal teeth. I however have very sensitive teeth, and found extreme amounts of pain when using these. Absolutely NOT for those with sensitive gums. I had pain for hours after.

This product really does work. It whitens without leaving my gums with a burning sensation. Easy to use and results are fast. My teeth got whiter within the first couple of uses. Would totally recommend to anyone looking for good whitening strips.

I love the white strips I used to use these all the time but I need to start using them again. Just be sure to have toothpaste for sensitivity. Other than that they did the job!

I use these for an extra boost. I have also used the sensitive teeth to see any difference and I didn't notice much. But I use these for one hour before big events and they help get any additional stains off.

This product did absolutely nothing for me, I used the entire box and was left with no different result, quite disappointed. Satisfaction not guaranteed, and still no refund. I would never waste money on these products again.
