Just because it's new, doesn't mean it's perfect. My advice is buy new, but buy from a retailer that has it already out of the box and tested.
So far on the metpro that is used by Pingraffix
1- 1st playfield starts to peel 2 hours into use
2- new populated playfield sent and installed
3- switches are not registering so I trace out the wires and find four wires going to the wrong switches
4-pop bumpers not working fixed by adjusting switches underneath the playfield
5-graveyard drop targets stop working after a few plays, look underneath and find the plunger unscrewed from the plunger
Re-assembled and used thread lock. Never happened again
Before this starts a bunch of bs
The woz we had, had just as many issues.
My point is that new games need adjustments.
