Hey, I'm new to this site. Just placed an order for the whizzinator, and some synthetic urine. Gotta see the P.O. soon. My question is: the bathroom i piss in is very small. He doesnt look directly at me, at least the front he doesnt. My concern is How loud is the snap that is heard when releasing the valve??? Please help!!!!! My freedom depends on it. There is also a metal detector in the lobby of the building, no prob for the whizzinator Right??????
