I'm not sure about the 3D white, but every Crest whitening product i know of, works amazingly well. My aunt and cousin have the whitest teeth, and my aunt has always used the original white strips and my cousin uses the 5 min(i think?) strips. I literally have never seen whiter teeth than theirs. I use 3D white tooth paste and i can't believe how white my teeth are. Also, their whitening mouth wash works wonders. FYI, i dont have sensitive teeth AT ALL! When i use this brand of whitestrips, even only one time a day, i get intense, sharp pains in my teeth throught the day. It's like a stabbing pain, even when i am not eating or drinking. GoSmile didn't bother my teeth at all. After all of that, i still would reccomend Crest over any other store brand(besides Go Smile.)

Good product. I use this teeth whitening strip when my teeth need to be brightening up. They stay in place on my teeth. Though the peroxide oozes out and it doesn't taste all that great. When I have the strips on I constantly have to spit because of the peroxide. And it will irritate the gums.

I just started using these and I am in love. They are so easy to use. I put on before I get in the shower and by the time I've Finished my treatment.

Love these. Definately noticable results after the first few days of using them. Some sensitivity, but taking a little break after a few days and then continuing does the trick.

I have used these strips and other crest strips in the past and I love them. I got so many compliments on how nice my teeth looked when I was using them. After a box or so my teeth were where I wanted them to be and so then I only touched up every once in a while. I did not experience and sensitivity to the strips and would recommend them to anyone who wants whiter teeth without getting the professionally done.

I love these whitening strips. I've used professional bleach and it makes my teeth ache. I switched to using these about two times a week and my teeth are very white and relatively pain-free. The stick to the surface of your teeth much better than their less expensive vivid white strips. So if you are looking for some basic whitening strips, I'd really suggest buying these and coupons are always available

This is awesome!!! My teeth are whiter than white and everyone notices!!!

I tried these on my daughter (shes 9) and after one use her teeth looked awesome. She was so happy about it since it seems like her teeth stain very quickly.

This works great and it's easy to use!1

I love it!! My teeth look whiter just with one use! I will defiantly keep using this.

I LOVE these! My daughter and I both use them. They work so quickly that I only use them 2 or 3 times a month and they keep our smiles white and beautiful.

Honestly, I always want a whiter smile. These whitestrips worked GREAT for me--within only 2 days I felt like I could already see results! They are sort of a splurge for me, but you really only need to use them twice a year to keep up the white smile; however, I got a coupon for some money off my next purchase of the whitestrips (as well as coupons for the advanced vivid tooth past, toothbrush, and whitening rinse--none of which I've tried yet). It takes 2 weeks (14 strips for top AND bottom), but its well worth it. Like I said, this product worked REALLY fast for me! I'm definitely pleased with the results and couldn't ask for better :) (hint: if your teeth are prone to getting sensitive like mine are when using white strips, I recommend using Sensodine toothpaste [or any toothpaste meant to decrease tooth sensitivity] for a few days before and throughout the two weeks you use this product; it kept my teeth from hurting at all!)

They work, but my teeth sensitive now I can definitely tell a difference in the color of my teeth, but I have to be super careful to not use them too regularly or my teeth are super sensitive. I've also had some trouble with keeping them secured on my teeth the entire time, but a cheap mouth guard over these strips works really well!

I started using these strips about 2 months ago and I love them. They do have a awful taste. They work very well and I started to see results 3 weeks after I started. I wouldn't use them everyday, but every 3days because they they sticky stuff can stick to your teeth.

These made my teeth really sensitive and they don't wrap all the way to my back teeth. But then again, those teeth don't show when I smile. They whiten your teeth, but they're not the same as going and getting your teeth done professionally. It's a good value for the price. I'd buy it again!
