Applying this product is very messy and time consuming. Will find charcoal in my teeth a day or so later. Also, my teeth and gums started to hurt at about day 2-3 because of the intense brushing that you must do. Pretty sure the recommend you use it daily which I do not like. Seems like a better alternative but would not recommend to to others. Wish I could return mine as well, but you cant.
