Quoted from PW79:That’s unsurprising actually
The troubled mechs are specific to the Premium/LE
I’m tempted to buy Munsters Premium & Maiden Pro
Took me forever to adjust mine to where the stupid orb ball hit every time.
the auto launch wasn't any easier, it's still off sometimes (but hit's a 90% average)
luckily I never had issues with the mummy lock.
I didn't hear this complaint to much (maybe because other didn't notice or some games were fine)
the loops didn't register 100% of the time. I had to add spacers to the bottom of the loop optos.
I recently saw a kit for sale on one of the pinball sites for this issue.
