Im very satisfied with this product and would definately use it again.
Easy to use and effective
The hardest thing is it's too hard to stay open my lips so I dont touch the paste with. I have to buy a dental mouth opener or something.... I have to use it more days to see the result.
Easy to use, no tooth sensitivity after & very fast shipping.
I love, love, love this product. It has changed the shade of my teeth from white to "Hollywood" white
