I ordered my Premium December 29 with an estimated delivery in March later narrowed down to the fourth week of March which came and went with no delivery. I was told Stern was waiting on parts, but a few will soon ship. I took delivery April 13.
I'm enjoying the game and only found one minor issue and another possible issue. The Start button didn't work. It didn't even light up. I played for hours using the action button to start games before I figured out that the inside of the start button, the actual button part, was dangling inside the machine. I connected it back together and that fixed that.
My potential issue is T-Rex. He functions perfectly and while moving vertically he has the typical small motor sound, but he seems awfully noisy when moving horizontally. Like he's straining with gears grinding. I sent a video to Stern support to get their opinion. I hope it's not normal because it's loud and sounds like it's on a path to failure - after warranty of course. I have the games volume loud to cover up the noise. I'm moving it using a flipper button while in diagnostics.
My only quibble is that white flasher lamp on the left which is blinding. It's worse than my F-14 Tomcat. There's an option in the adjust menu to reduce the brightness, but it's not enough. I finally took that clear dome off and temporarily popped a red insert I had lying around in it's place. I'll either be replacing the dome or the led board with blue depending what I can find.
The game is fun and makes my old "Fast and Furious" F-14 Tomcat seem geriatric, but that's another topic.
I installed the over priced Jurassic Park topper with a slight modification. Here is a pic. Don't be cruel.
