Noticeably white after just a couple of days! For the results the price is very reasonable.

These whitestrips are great! They always leave my teeth whiter and are super easy to use.

Great for any last min whitening! :)always use these when I have an event!!!

I believe that this product truly works cause I've seen them work on some of my friends.

These leave your teeth sensitive, but do their job. They are super expensive though.

I've used them a few times and they are okay. They don't make a huge difference the 1st time though

I have used this product multiple times. Always whitens my teeth. Easy to use and not expensive.

Weird keeping them on but if you really stay at it you can definitely tell a difference

This made my teeth so white. I got so many compliments on them. I will definitely repurchase this

I got great results with these strips! My teeth look like I had them professionally whitened!!
