Both coil stops on my Deadpool have already broken. The nub came loose and eventually caused the flipper to start sticking. It has about 1400 plays on it. I've also never seen plungers mushroom so badly, so quickly, so either those are crappy as well, or perhaps the broken coil stop causes them to deteriorate more than expected?
I've also had to replace both on Iron Maiden in under 4000 plays.
Flippers should not need to be rebuilt that quickly.
This is much worse than any of my previous Sterns. I'd guess that GOT and GB got rebuilds around 7000-8000 plays, and their coil stops were still intact (albeit pounded down and in need of replacement). I don't believe I've ever seen this issue on any Bally/Williams I've operated.
I realize this is a pretty easy thing to replace, but it's a pretty crucial part to be wearing out completely in under a month.
