I hate these. They always fall off of my teeth. They're not effective at all. I don't recommend purchasing.

For an OTC product this does a great job and whitening your teeth. This is the best whitening product for those on a budget.

Simply the best in at-home teeth whitening products! Highly recommend during this time of COVID to get that “straight from the dentist” sparkle!

This whitestrips do a very good job and the best thing about them is their ability to stick to the tooth surface and stay put.

Have used these in the past. They slide on your teeth a bit. But the hydrogen peroxide does the trick. I've seen fabulous results with this one!

It's good a good product, but I stopped using them after 4 days. My tooth got so sensitive and I start to feel discomfort.

Works very quickly and efficiently. If you have a big event and need to whiten fast these are great!

These white strips work almost instantly! They leave my teeth extremely white. I use these when I want a quick pick me up.

I'm a smoker and a coffe drinker and my teeth stay white with this awesome product! Thank you crest .

I am constantly drinking tea, thus my yellowish teeth. Crest whitestrips turned my teeth from yellow to white!!
