I have always had a problem with whiting strips not working. This product did not meet my full expectation but I did see some results. I would recommend this to anyone wanting small results but if you want your teeth really white this is not the product for you.

These are very very expensive. I am not a fan of the price that they do get the job done. I also did not realize at 1st that they are a treatment and each strip is to be used in sequence not once every once in a while. I was not aware that eater Box was a sequence of treatments not just one treatment every now and then

I loooooveeeeeeeee these so much! They work and the one that comes with the little stick to boost whitening is awesome (I'm not sure if this is the specific one) but it definitely does weaken your enamel, i can feel it when i drink which is why i stopped using it !

I've tried everything to get perfect white teeth! My teeth were always a light yellow color, I never wanted to smile with my teeth I was so not confident with my teeth. So i decided to buy the teeth whitener. Best purchase I have ever made! Now I can be happy with my smile. And very confident. I get compliments all the time now about my teeth, and about what I did to get them so white. My answer is, "Crest 3D whitening strips!"

Same as most commercial whitening products, the sensitivity is what gets to me the most. I love the the results, but suffering from multiple hours of tooth sensitivity makes this product hard to use on a regular basis. I guess that's just the price you pay for blinding pearly whites.

These are a MUST BUY. I've been using them on and off for years and they are absolute miracle workers. I only need to use maybe a third of a box and then my teeth are SPARKLING white for literally a few years. A great, cheap and easy way to get white teeth.

I love how easy these strips are. I definitely noticed my teeth looking brighter within a few days. The only drawback is that it does add some sensitivity to my teeth. Love how easy they are to apply and how many stores carry them. I feel like they are a little pricey but they do work well.

Love my crest white strips and honestly couldn't live without them. My smile is something I take pride in and this is my secret to keeping white teeth. They are very effective if you use them the way they are intended to be used. Easy to apply and not uncomfortable at all.

I was excited to try these but after just 3 minutes on my teeth, there was a super sharp, radiating pain. I've never thought of my teeth to be sensitive, but with this product they were... definitely don't get this if you even THINK you might have sensitive teeth.

After 4 long years with braces I finally took them off a couple months ago. I thought I was going to have that wow factor but I didn't really get it. After applying the 14 day crest 3D white, people started to actually notice my braces were off! My 3D smile made me the happiest guy alive!
