Do Crest 2-hour 3D Whitening Strips really work?

[kotabearsmama]

I just got some at Walmart, but didn't get the toothpaste + mouthwash to go with it because I didn't think about it at the time and we were in a rush. I have some Optic white toothpaste that I used before putting them on (bad idea, didn't know it wasn't recommended lol) anyways, since I can't do anything about that, if you've tried them, how well do they work?

I just took them off about an hour ago and they worked pretty well! 3 left to go. :)

They work ok. My teeth are sensitive though so it was hard to leave them on for 2 hours and my teeth hurt for an entire day :(
