My MMR was built 1-26-2016 and is SN 713. It has probably 80% of the inserts that are nearly transparent when lit. I don't understand why some have opaque white under them and some do not. I'm enclosing photos below. Notice how much nicer the ones with opaque white look as compared to the transparent black ones. If not a playfield swap - I'd appreciate a rebate. For sure this affects the value of my new machine. Years from now, some prospective buyer will say, "Oh, it's one of THOSE".

You know what - you are right. Aside from some low density insert printing, this machine is FRIGG'N AWSOME!
