Quoted from Calfdemon:

You need to take into account that most of the posts in the owner's thread are from the folks who need to do things to their games and are asking advise, complaining, making adjustment recommendations, or whatever. If you actually counted the physical games that there are posts regarding issues, there are probably 20-30 games or so total and most only have a minor issue or 2. Only a few have posted multiple (major) issues in one game. They are in the 300's right now and taking build sheets for the 400's already.
That means there are probably 300 games out there that you have NOT heard from, because the games are playing fine. Granted, not everyone is on Pinside, but still. The posts you are reading relating to problems are not from everyone. The reality with forums is that you hear when there are problems, but not when there aren't. It gives the false impression that every game has issues. I wouldn't worry too much as most of the games only need a small little tweak here and there (like any other NIB game), but you will probably be fine when you get yours. Don't let the posts in the owner's thread get you down. And take more stress off knowing that even if you do have issues, you bought from Spooky who has some of the best customer service around. They always make it right.

I would put it more on the lockdown system to blame, or make the hook ends longer.
The springy clips can allow the hook out.
With a proper lockdown bar system the lock is positive, not just spring tension.
Also the new stern like setup gives no support underneath for the bar to rest down on, and relies alot on the side rails and glass.
Once the lockdown hooks have come out, no the playfield rails aren't meant to hold the full vertical weight and in shipping.
I'm glad there are no bolts like DE games.

For a fairly straightforward DIY fix for the LED strip diffusion use thin white styrene cut into strips and attach (hot glue works) directly over the LEDs. I had some RGB speaker light rings years ago that had the same issue, and I just cut up an old "for sale" yard sign I had laying around which diffused them nicely.
