great whitening strips. they help maintian my whiteness without stripping my teeth. I don't leave them on the whole time suggested though because my teeth do get sensitive.

Whenever I use them, I notice a difference after one use. Sometimes I experience a bit of tooth sensitivity but then I limit my use. But I love this product and use it frequently.

For a product that you can get without going to the dentist, crest is great. Very effective depending on how much you put it on. But if you leave it on to long or use it too much it does make my teeth sensitive

This is my go to teeth whitening kit. I see results after one use! It's not dramatic but you can definitely see the difference. I use everyday for a week and then every other week.

A once and a while buy for me because of the price, but a great purchase for rapid results. After using them for a while, my teeth got super sensitive to hot/cold, so that is a downside.

This product did absolutely nothing for me, I used the entire box and was left with no different result, quite disappointed. Satisfaction not guaranteed, and still no refund. I would never waste money on these products again.

Does a decent job at whitening your teeth. Has a harder time with the stains at the base of your teeth near your gum line, but repeated whiten does help lighten these stains. Using these in combination with their other products does produce results.

I have been using this product for ever. I highly suggest it it works so well! It is easily found at most stores and works just as great as professional whitening sessions at your dentist!

This teeth whitening product is high quality for the price point. You get quite a few uses from it and I definitely notice a difference in the color of my teeth

These little things I carry with me everywhere. They're so great for traveling and even running errands in the car. I use once every other day and have the most perfect white teeth!
