We have sold close to a hundred woz's. When I talk to customer's that have them in arcades. I am told they are one of their most reliable pins. I have proto type number 2 that still runs in my shop today. It's been hauled around to all the pinball shows. Has thousands of plays on it. I think they are a very reliable pin. Especially if you look at what's in this pin compared to other pins that are out there today.
