Very bad seller, product delivered is not corresponding due to seller mistake, missing graduated red, sent 2 orange, missing sunset, sent 2 GND8, seller refused to send the missing filters. Wide angle bracket is also very bad quality, the ring is smaller than the bracket and will easily fall down from the lens. Keep your money and don't buy from this seller.
Not used item properly yet but seems good quality for the cost. Had to wait a while for delivery but happy with the item once it arrived.
