I noticed it right away when the doctor told me to start inflating. When I would squeeze the ball it would make like a popping sound and it would work most of the time. If it did not pop you could squeeze the ball and nothing would happen. So I would press the release button over and over back and forth from the ball to the release button until it would pop again and it would work to get a full hard erection. But then I noticed that if I left some saline in the cylinders, it would work all the time. If I deflated it all the way is when I had problems, until it just quit completely after ten months. So they replaced the pump and the reservoir with a bigger one.
So far it is working perfect. Smooth compression on the ball and easy to fill the cylinders.
