Work well. I don’t use these too often. But i often get compliments about my teeth. The Colgate whitening toothpaste and these strips help keep y smile bright.

Although they are a little pricey. They are definitely worth the money. I notice a huge difference in my teeth when I use these weekly. I do notice a bit sensitivity, but nothing too unbearable.

This is amazing and it’s totally worth the money! I have never felt more confident about my teeth! It didn’t burn my gums which I feel most whitening products do. It was amazing and my teeth look great!

Does a decent job at whitening your teeth. Has a harder time with the stains at the base of your teeth near your gum line, but repeated whiten does help lighten these stains. Using these in combination with their other products does produce results.

I like these a lot! They do help your teeth look whiter but not instantly, you have to do it a few times before you see results. You can run out of them fast but the price isn’t to pricy to keep up on it!

I definitely think these work and the box comes with about 10 whitening strips. Although using too much (just like any whitening products) makes your teeth sensitive.

I have used Crest strips before, however, these particular ones are garbage. They don't stay on your teeth like usual, it is like they are old or out dated and don't work correctly. Would not order these agian.

These whiting strips are no joke. They stick really well to your teeth so they don’t budge after you place them. They aren’t bulky like some strips can be and at times I have forgotten I was even using them.

I used both the professional express whitening treatments and the 1 hour express whitening treatments . The second one worked very well for me and I started seeing the results right away. But with the first one I didn't see a big difference

Crest whitening strips are gold!! I use once a year and my teeth stay very white. I drink tons of coffee so it’s a great products. I have been getting compliments on my smile for years and I owe it to these!
