Crest strips are definitely pricey but worth it if willing. If you have sensitive gums, it might be bad, but these strips definitely do their job!

These definitely made the surface of my teeth whiter, I do think that I made my teeth slightly sensitive for a short while

This set tastes awful but you can see the difference after a couple of uses. Unfortunately it makes my teeth sensitive.

Obsessed with having white teeth, loved this product, the taste is odd when you take the strips out but not unbearable. I would absolutely use again.

Loved this product! I used it sparingly since I do have sensitive teeth but had no trouble with it!! Noticed a difference in a few days!

I love this product keeps my teeth white. A bit pricey but you get what you pay for and it's a great product! I recommend

So easy to use and works wonders in my teeth. It is really affordable and i love it! I think if i would change something it would be the after taste

These really do the trick but they really were hard on my sensitive teeth. My teeth hurt for a few days after and we're really sensitive.

They do the job and make my teeth noticeably whiter after each use. My only complaint is they are not the most cost effective

They do help slightly whiten your teeth. For the price I don't think they are the best. They also made my teeth sensitive.
