I've had issues with the ball sometimes coming out of the inner loop so fast that the ball hops over the flippers and drains. It doesn't happen all the time, but it when it does I'm in the middle of a really good game. I've seen it on my example and several others, so I decided to custom make a protector that covers the area above the flippers to prevent this from happening. I had 5 made just in case some others might be interested in it. It will fit all models. I'm selling them for $23 including shipping. Please PM if you are interested.
