I love these they work and I've been using for years they are a little pricey since the price of a professional whitening has lowered in the recent years but I always have on hand when I feel my teeth getting dull

I like to use these whitening strips for a couple of weeks before an event. They work quickly, and results are noticeable in a few days. I wouldn't say the results last forever, but definitely work if you use consistently.

Love how this really whitens my teeth. Only con is that even after using Sensodyne toothpaste for months, my teeth are still hurting the next day after using this product.

These strips made my teeth super sensitive. I used them for 3 or 4 days and then had to stop because my teeth were too sensitive. I wasn't noticing that big of a difference in whiteness either

This product delivers on its promise. When used as directed, it whitens your teeth without causing sensitivity. Results are noticed quickly. I like to use twice a year but sometimes the whiteness lasts longer!

AMAZING teeth whitening product! I absolutely love these! A little pricey but totally worth it. These don't have the awful taste some other products do. The results last much longer than comparable products.

These Whitestrips are great!... as long as you don't have sensitive teeth. I do not, so I always keep these on hand for a quick touch-up and I'm able to achieve a few shades of whiteness!

I. LOVE. THESE. They keep my teeth white for a whole year. They don't have that horrible teeth-whitener taste, and they give my very little sensitivity. I won't get any other whiteners!

These work well, they adhere nicely to your teeth and don't slip off or move around which can be highly annoying. Not a bad flavor and definitely have bumped the shade of my teeth up !

I do love these whitening strips but like most whitening products, they make my teeth super sensitive. After using these my teeth are noticeably whiter though so I do still like the product I just already have sensitive teeth
