Work really well for me! Good grip on the teeth so they don't slide around. They don't irritate my gums like some whitening products

This is great to maintain your already whiten teeth but if you have yellow teeth and want to whiten it's gonna be a long time

I got my teeth professionally whitened and it did nothing compared to when I used these! This is better than a professional whitening at the dentist!

I have hardly seen a difference in the color of my teeth and this has left my teeth feeling so sensitive! Would not recommend!

These work very well! You can definitely see a difference after just one use. It makes my teeth a little sensitive the next day though.

It works just the way its soposter and its grate it whiten just as it says it will would buy it again in a minute

My smile and teeth are important to me. Crest 3D White Strips Professional Effects help me feel confident when greeting people and smiling.

I'm so happy with this purchase, my teeth are dramatically whiter. I'm a big coffee drinker but now you can't even tell!

I've noticed a good improvement with this product that works relatively quickly. I get lots of compliments about the noticeable difference

I love how simple and easy it was to place them. You can have them on while doing chores. Worked 100%. I recommend it for everyone
