Really hard to use and made my gums super sensitive. I don't enjoy that these strips slide right off my teeth and don't seem to whiten effectively. I wouldn't spend the money on this again.

Honestly, I've never been in such tooth pain. Used it ONCE for the correct amount of time, and the pain kept me up all night. I still can't eat or drink and it's the next day. My teeth are on fire and my gums are throbbing.

These are one of the first white strips i've noticed a huge difference with! They aren't the best for sensitive teeth so maybe don't leave them on as long if that's a problem for you!

I wish I could see more of an improvement with these white strips. They do make my teeth more sensitive to hot and cold. The price isn't over the top but I don't know if I will keep buying these

They made my teeth a lot whiter initially, so yay, great for job interviews or picture day or whatever, but it faded quickly and left some sensitivity issues, and also it's pretty expensive.  So YMMV. 

I love using these the week before a special event when I want my teeth to be brighter. They are very easy to apply as well as remove and they don't make my teeth feel too sensitive afterwards!

I am a huge fan! I used these whitening strips before prom and have been using the monthly touch up strips for a few years. So many friends have commented on how white and amazing my teeth look. It is worth every penny and is a great Christmas gift!

I've always had a bright smile, but after using these I️ could see the results! Easy to apply and easy to take off. Easy to do at any time of the day

Crest 3D White Luxe Professional Effects Whitestrips Teeth Whitening Kit are amazing! You get results that match what you would get in a dental office at a way more affordable price. They are pretty easy to apply and stay in place.

I love having white teeth at all times. I'm a repeat user and will continue to use for sure! I alternate days to prevent teeth from becoming too sensitive. They work fabulously for me :)
