Shipped by so fast envelope. Nothing to say, works normal. Although better price than at the surface, provided to buy at least two batteries (same internet provider, to cushion 1.5 to pdfs). A surface of this stack style = 3 (at a minimum, after haggling -_-) or the same as if caught in the unit here but with a 2nd battery is amortized 1.5 as delivered together :)
