The stips seems to be working, minty flavor.

I have tried a lot of whiteners and none have whitened as much as this brand did. I got instant whitening in one application, so I know I can get even more whitening over time. I have coffee and tea stains, as well as, smoke stains and they are not easy to remove. This actually worked on the stains so that they have reduced by half.The strips are easy to apply and stay put.The only bad thing I wish was, it was a bit sweet for me, but not something that will keep me from. using them. I will definitely be using this brand.

These strips work well for what they are. Don't have high expectations, though.

This is my second box. This time I ordered 42 because I ended up having to share with my husband. I did see some change, I think. My teeth were already kind of white but needed a retouch so I will come back and write another review about the second set of strips I just received yesterday.

I didn't notice a significant difference in the whitening of my teeth but they at least tasted okay.

If I could give zero stars I would. Can’t even keep the strips on for ten mins because they slip and the product on the strip gets everywhere making it impossible to keep on for 30mins
