Quoted from Boof-Ed:I know it doesn’t really affect gameplay but I enjoy looking at my games just as much as playing them and the light from the backbox reflecting off this looks like $h!t.
You can turn down the backbox brightness to minimize any reflection, not that it fixes anything. We noticed the ribbing on my buddies AIQ pro when inspecting it when new, but really has not caught my eye since and it seems to be holding up well. We just have fun playing the snot out of that pin. (we have his backbox brightness set ~ 10% attract/ 5% during play, so maybe that's a thing!) Hopefully Stern will get it sorted out sooner than later.
