Teeth whitening: Whitestrips only whiten the flat areas of your teeth. The most effective method for whitening teeth is tray and/or in-office whitening delivered by your dentist.

In office > strips: The whitening strips can be effective but if you want faster, more noticeable results, you would be happier with an in office, professionally administered whitening treatment like Zoom, Kor, Saphire, or any of the many systems offered by dentists in your area. You can always find someone running a special if cost is your main concern.
