Do Crest 3D Advanced White Strips (the professional effects ones) actually work?!

I only got a chance to use the one sample of a 3D white strip and I swore up and down it worked like you wouldn't believe. I don't smoke, but I do drink coffee and dark pop. I don't staining on my teeth but the strip made my 'grill' look like amazing after a short application.

I do use the 3D white toothpaste and love it! It works amazing.
