"Gun sight" aiming quite accurate, but difficult to see in the dark - might need a little red light to assist.
Just checked the cost as I threw away the paperwork. Might be USD15, but it cost me AUD55 to get each one of two into my hands. I've heard of one larger order coming into Australia - perhaps some will be available are a more reasonable AUD price. I would think that AUD30-35 in hand would be very reasonable.
