There isn't much to say, the product does what the description says it does. I must say the shipping on this is ridiculous but at the same time well worth it. I used it on two kids all white sneakers before going to a party and they still look brand new, not a spot on them. If that is not enough of a test I don't know what is. I also used them on a pair of all white air jordan's and have gone to a concert at the beach and a bbq and they are spotless. I would advise trying to rub stuff into the shoes because I dont think that would end well.
