This product is incredible! I am so impressed by these whitening strips! They work so well that I can tell a significant difference after just one use! You simply apply the top & bottom strips to your teeth & leave them on for 30 minutes. Personally, I usually leave them on for about 15 minutes because I get impatient, and the results are still amazing. My teeth are much whiter, and I'm thrilled! You seriously need to give these a try!!

I first received this as a sample and then i saved yo some money to buy full size. Its okay it did whiten my teeth but most of the results i had seen wasnt permanent it was effective but only temporarily if im going to biy something this expensive i would expect the results to be permanent. I like it only if it was permanent results.

A little pricy, but I did notice a difference in my teeth! I've used these a few times when I have an event like a wedding coming up! It for sure works the only problem I had was after using this I had some teeth sensitivity, but besides that great product!

This product works great to whiten teeth. The strips actually adhere to the teeth so it does not move around a lot while you are using them. If you tend to have sensitive teeth or sensitivity every once in a while do not use these strips back to back.

I have experimented with many different "whitening" products, including the professional trays and product you get at the dentist. The professional stuff definetly worked but is much more $ in the end (trays and gel). I liked how this product stayed put, and I didn't leave a nasty taste in my mouth. The best part is it's 30 minutes, and not an hour! Crest has definetly improved their product with the "stay put' strips, and the effects that it has after just 1 use! I did my first application this evening, removed the strips and my teeth just look brighter!!!! An A+++++++ product!

This product makes me want to smile all day because of my white glistening teeth! I love this product and unlike some other brands, it doesn't leave a grainy feeling on your teeth! Would totally recommend this product to you guys right before getting pictures make or just to feel more confident I your smile!

The crest white strips are a great and easy way to whiten teeth, the products does a great job in doing its job and I have used them a few time, but to keep the results you have to use it often and I don't like how hard it is to keep the strips on your teeth. Also I wish they would make them with better more natural ingredients..

They are a little pricey but I like it. I honestly like their newer toothpaste. It works better than this one. It's Crests' Pro-Health HD steps one and two. I noticed visible difference. Going back to the white strips, I like it. You have regularly use it to see change.

so i purchased this. i used 4 treatments four days in a row and I noticed that my teeth looks really white. However, i forgot to keep going and used the strips again after 5 or 6 days. my teeth went back to the old color after 4 days after using the first 4 treatments. so now i have five more to go. i really wish i used the 14 treatments for 14 days in a row. I'm not sure if my teeth will go back to the same/yellowish color after doing the 14 treatments again if i purchase another kit.

These strips are AMAZING! I used them every day, for the 30 minutes, and when the pack was gone (actually even after the first use) my teeth were SO much whiter than they've ever been. The strips also don't slide or slip and have great grip so you're able to talk and not feel like you have to keep your mouth super stiff to avoid having them slip off.
