Hey Thanks Christy! It does have the little black piece and the O-ring.
Only I don't understand how that bracket thing in the picture will attach? The attachment is on the side not the back ????And how does it stay on the glass????
Sorry If I sound kinda stupid?? I search but what I find is magnet mounts but they don't look like they would work for this one???????? Does that make sense?
