Review title: Great Deal!
Product review: If you want whiter teeth and you're not on a time frame, this is a GREAT product. I use it every morning for 15 minutes while I'm getting ready, and it keeps my teeth nice and white. With 84 strips, it lasts my husband and I about a month. If you used them twice a day, I'd say you would see a huge difference in one week.
