Quoted from Thermionic:Yes, the parts Stern has been installing for roughly three years seem to be decidedly less durable than previously, but it really only impacts the flippers (in my experience). Periodically inspect the bottom of the cabinet under the flipper area and if you see an increase in metal particles/dust that is your sign that the stops are probably on their way out. Ideally you want to replace the stops before they fail in order to avoid any collateral damage, but I have had several outright failures and not experienced any additional problems.
I get replacements at https://www.pinballlife.com/flipper-coil-stop-for-sternsega.html and they seem to hold up better than the stock ones; I suggest keeping a few on-hand so you can keep the party going when one lets go at 11pm, it only takes a couple of minutes to replace one.
I saw someone say that if you move the spring washer to the other side of the coil it can prevent this problem. Some other people thought they had a bad batch of stops but it seems like it's an ongoing issue still.
Only issue I've seen with godzilla are pretty typical things where adjustments need to be made on some of the moving mechanisms etc. Seems like a fairly solid machine so far.
