I use this product every 6 months. They work very well. For the price they are a great value. All surface stains are removed and my teeth are super white.  I love this product!

Definitely notice a difference in the color of my teeth, however my teeth are always a little sensitive after for a little bit so I wouldn’t recommend if you have sensitive teeth.

Great whitening results in a short amount of time. May cause some sensitivity if you have sensitive teeth but you can use it every other day instead of every day to minimize any side effects.

these work really well, i used to hate doing these as a kid, but they must have changed the taste of the product because it’s bearable and it truly whitens my teeth. i would 100% buy again and recommend everyone to buy this product.

Works great but not the best for sensitive teeth does start to hurt after a couple of uses would use again though it whitens well just have to be careful not to overuse them

If you are trying to find a way to brighten up your teeth at home this product is the right choice. It is easy to use and the directions are real simply to read and follow. You will start to see results in about a week or two .

This is by far the best whitening product I've ever used. The strips stay put where you want them to, and within only a few days of use I could see a drastic change. I would recommend this product to anyone!

It worked to whiten teeth a little after one strip but I had tooth sensitivity for a few days. Not looking forward to trying again but it was not a value item so I don’t want to waste it. The strips did stay put until taking them off.

Very pleased with this brand and product. Keeps my teeth free of stains and yellowing, and is quick and easy to use on your own in the comfort of your home. I use it maybe twice a week and notice a huge difference.

This product helped me so much. It really works, it made my teeth pearly white and I have gained my confidence. Using Crest 3D strips motivated me to not eat or drink anything that would damage and stain my teeth. I loved this product!
