Teeth whitening?

Well i just bought teeth whitening strips and they are the ones from crest, do this brand actually work. What would be the best brand or is there a better way to whiten my teeth. I want it to be white fast but i realize it takes time. You can tell me as much as you know about teeth whitening to me if you want

I don't like those Crest strips personally. I love Rembrandt "2 Hour Whitening Kit." Its pretty cool, because you can form the teeth trays to your own mouth and you don't have to worry so much, unlike the strips. Its about $20 but I always get it cheap at Target Greatland. Also, I love to brush my teeth with Rembrandt "Intense Stain" in the morning and use Crest "Vivid White Night" when I go to sleep.
