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.

This I don't know. My guess would be that most of them come from the same place, but I really have no evidence for that one way or the other.

I wish I had done a better job keeping notes, because I'm now pretty sure that I've actually replaced the right coil stop on Deadpool TWICE in 1400 plays. That would mean the replacement (which would have come from Marco or PBL) I used was also really poor quality.

There could be something different about Deadpool, but I hadn't made any adjustments. When trying to figure out why a flipper was sticking the other day, I did notice the coils and plungers were extremely hot, even after the game hadn't been played for a few minutes.

I should also say that aside from this, my NIB Sterns have been exceptional. Aside from any initial adjustments (like the battering ram in GOT, or Slimer in GB), games are generally going many thousands of plays without needing anything.

Totally possible. It would be hard, if not impossible, for them to receive a new batch and then test many thousands of times before giving the okay.

Not so sure about this. New games always feel stronger to me but I always chalk it up to brand new flippers and a glassy playfield.

There was an alignment issue with the plunger so it wasn’t striking the ball cleanly and plunges would go all over the place. The chip happened right there in the shooter lane, and I blame the alignment. Plunging was very inconsistent and I chose not to do anything about it. My bad. Not that big of a deal.

While we're talking about this kind of thing...

Any suggestions for what to do with Stern buttons that stick? Like, you try to flip but the button doesn't depress and then you mash it hard and finally it loosens up and works fine for the next 50-100 flips.

Upper right flipper coil stop on my JP needed to be replaced in under two weeks. We're about a week past that, but I could do some math and figure out the flips.

Two of three replaced in JP so far. I moved the spring washer on one but not the other one. Will see if that makes a difference.

The coil stops are different sizes, so you'd have to change out the entire bracket I'd imagine. The distance of flipper travel would almost certainly be changed in the process. Wouldn't it?
