I've used this in the past. They're easy to use. Didn't whiten as fast as I thought, but I didn't use them the full time period and duration.

Love this product so much that my family got a bunch for me as a christmas gift! easy to use and keeps my teeth super white

...the lower strips are too short. It would have been nice if they were as long as the upper strips.

They are super easy to use and show results very fast! I keep them in a little longer than recommended for better results. The strips fit most teeth

Definitely you see a big difference in the whiteness of your smile and while they are expensive to me they are very worth it

I used these a while ago and didn't notice a big difference in my smile. I also have heard that it can be harmful for your enamel.

This product is great; it's quick and easy application. Only con is that it leaves my teeth feeling sensitive afterwards.

I love it taste isn't too good but works well and White's within 2 weeks my teeth went from orange to white I recommend

These are great! I definitely noticed whiter teeth after using a few times. The only thing was that I had tooth sensitivity.

Love these strips. So easy to use and fast results! I use them about once a year to keep my smile bright.
