Just received my GB Premium today and have been setting it up. Interestingly most of the issues I have read about seem to have been taken care of. Namely, reinforced metal brackets for cabinet strength and the metal pinball launch mech now lips over the wood meaning the wood doesnt get hit by the balls. I have attached a couple of photos.
Love the game... so many options etc. Levelled it out and game plays perfectly, can hit ramps on each side etc.
The only things I have added are metal protector in shooter lane and airball and projector protector.
