Whiter teeth after the first use!
I've tried whitening strips before and they haven't worked for me. This one is like the ones you see in the ads which usually costs around $100 but this one is less than half that price! After the first use my teeth were whiter and within 5 uses, about 3 to 4 shades whiter, removing most of my stains! Love this product!
