Great product! Make sure to use this product as instructed or else it could cause some sensitivity in your gums. Overall I definitely saw a difference in the color of my teeth.

I've seen these whitening strips everywhere and I finally bought them a couple weeks ago. These whitening strips left my teeth so much brighter than before and didn't hurt my gums at all.

Definitely whitened my smile. But it might will make your teeth a little sensitive. I had some sensitivity and had to do them every other day/ two days.

Best whitening strips. Use them maybe once a week and they work wonders. Use them regularly with whitening toothpaste and it gives you pearly white teeth

I've used this product many moons ago and it didn't work the miracles I thought it would but I guess you can say for an over the counter, I was satisfied. I'll have to try them over again since it was years ago and they've made so many advancements

I recommend any of the Crest Whitestrips. They work just as well as the products dispensed in dental offices, it will just take a little while longer to work.

The new strips are awesome! I have used the regular strips in the past and I found that these stay in place much better and work much faster. I could really see an improvement in my hubby's teeth after one use!

These waiting strips are a van tastic they are easily accessible you could Byam pretty much anywhere. The results are great you instantly see whiter brighter teeth. But keep in mind if kept on for too long will make teeth are very sensitive.

This really does whiten your teeth as long as you are consist with using their same products. i finally have my pearly white smile that ive always wanted

Don't try whitening your teeth if you have sensitive! I tried it worked, and tooth became white but I had sensitivity on tooth for a week or more after
