I used Crest whitestrip after hearing of a friends experience with the product. They really seemed to work, even after a few days I could notice a difference in the whiteness of my teeth. I love tooth whitening products, and this one is so easy to apply, and the thirty minutes that it took could easily be fit in - while you are working before going to bed, or watching television, or even driving your kids to school!
Compared to the price of a usual teeth whitening session, it is a great price - and with results that were quick, and great results at the end of the ten days it is a great alternative to in office procedures to whiten. I will use this product again, more than likely continue to use it a couple of times a year for optimum results, and to keep my teeth nice and white.
I didn't notice a strong taste, and it left no residue - Overall, very impressed with the product!
