I really like this product and it was recommended to me by others. It made my teeth really white which I love! I have sensitive teeth so if I need to space it out between using. It can hurt your teeth if you use it multiple times a week. It's worth the price because it comes with so many!

I recently started using whitening products. I heard from a friend that and she highly recommended it. I see noticeable results just after one use. I try to use them twice a week because I have sensitivity. So that's my only downfall but that might just be me. Try it!

This is my secret to super (but still natural looking) white teeth!! I have sensitive teeth so I could only use them once every three days but it was very worth it. The last time I used them was August of 2016 and my teeth are STILL white and I receive multiple compliments. There are higher in price but they are worth it!!

[This review was collected as part of a promotion.] I received the Crest 3D Whitestrips for free from Influenster in exchange for my honest review. After using the Crest 3D Whitestrips for one week, I definitely noticed a visible improvement in the whiteness of my teeth. The color looked noticeably brighter, especially around the edges where I had the most staining. However, I did experience bad sensitivity throughout the week—mainly sharp zaps during and after the treatment. While the results were great in terms of whitening, the sensitivity was tough to deal with. If you have sensitive teeth, I’d recommend using them every other day or following up with a sensitivity toothpaste.

I've been using these since march 2015 and I inmediatley noticed my teeth to be whiter but it wasn't until I compared pictures from before and after that I realized how much whiter my teeth were. They really work and now I really have a more luminous smile. I think I'll start using two packages per year so I see even better results

I am beyond amazed by the Vivid whitening strips! My teeth were so stained by a gum treatment that I had and it literally took my teeth from YELLOW to a pearly color. I just purchased the professional strips to take them from a beige to a white look! Best purchase! Worth every penny!

Idk man these things work, but they hurt your teeth if you use it more than once a year. I used this after getting my braces off in high school and again before my wedding and had great results both times, people noticed and complimented my teeth but it hurt to let the air touch them.

I use Crest 3D white luxe glamorous toothpaste and I must say it works wonders. I was using another brand's toothpaste that was alleged to whiten your teeth but instead what it did was create dark lines on my teeth. Once I started noticing the lines I switched to crest 3D white luxe and I noticed it removed the dark lines on my teeth and my teeth were looking whiter. If it weren't for this toothpaste, who knows how my teeth would look, I highly suggest this product!

I love using these teeth whitening strips. I put them on when I'm brushing my hair and leave them on for 15-20 minutes. They work but you have to stay on top of them and do them daily in consecutive days. They also are super expensive to buy . But you can get them at a drug store.

I love these. I use them actually two or three days in a year and people stop me on the street asking me if my teeth are veneers or they compliment me on the whiteness. Oh leave them on the recommended time. A few times I left them on much longer in time and it made my teeth so sensitive, omg. I recommend it !
