Quoted from Manny65:

The original run of Pro's had the artwork under the posts and the thicker clear. They changed this for the LE's (all Premium's were manufactured after this time so none will have the art under the posts or the thicker clear). Even with the changes to the PF manufacturing, there was still the chance of pooling and chipping around the ball guides and aprons, as they were being over tightened and the guide/apron edge was being pulled down into the clear. That said the issues that were reported online were far far less than what was seen with the original Pro's. Not sure if any of the Premiums suffered this issue and those receiving NIB machines more recently haven't reported any issues with PF (they've been quite positive about the overall quality).

Quoted from Flasher:

So far, yes. It’s a great game.
Mine had some minor scuffs in the playfield from either testing or buffing. I waxed it before the first play and it looks fine. The balls it came with are cheap so I swapped them out for some better ones. It took the 2.5GB code update without issue.
Perhaps it’s just me but I feel the inserts don’t look as high quality up close as those in my Stern ST or Chicago Gaming MBr but they look fine from playing distance. I would be curious to know what others think about the insert quality tho?
Enjoy your machine.
