With the title all is actually said. The product does what it is intended; it provides in the winter for a clear view! Unfortunately, that is, the means that exist in some supermarkets or hardware stores, rarely the case. I've been using some "Specials" thrown enough money out of the window and as a result streaks on the windshield. It pays off to use this brand products, as good visibility in winter when the long nights and often wet roads is simply a safety aspect.
