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. 

This definitely whiten your teeth but are hard to rip off and kinda pricey. I've used this many times. Makes my teeth pretty sensitive so that's uncomfortable. If it didn't cause that I would say it is 5 stars

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

I've used these off and on for 5 years. They're my go to. They seem pricey, but you can see the effects after just one to two uses. And they stay white! Would recommend for anyone. Warning: your teeth will be sensitive

I feel like these actually worked, but after a few times I got sharp pains through my teeth and gums when using, and it hurt so bad that I've been scared to try them again.

they have worked so well for me these past months. i have seen a huge difference. expensive to buy but def worth it. comes with a bunch of strips. i will be buying again soon!

Leaves my teeth w good shade lighter however it makes them and little sensitive but thats normal and expected. But I wouldn't recommend to someone who can't take the pain

this definitely worked and my teeth were super white. the reason i gave it only three starts is because it made my teeth really sensitive after and i don't think it's safe for your enamel.

Nothing beats Crest Whitestrips, NOTHING! If you are trying to whiten your teeth skip the gimmicks and just go straight to the white strips. It's not even worth trying anything else because this stuff is the GOAT

absolutely work! if daily brushing and flossing isn't keeping your teeth white, this product really will. It can be uncomfortable at first because of the band and how the product activated on your teeth, but you WILL see a difference!
