If you are referring to my post from earlier, I was super careful, watched @Jenius video repeatedly and had the instructions out, but I think I got unlucky with a fault in the hinge area that nothing could of avoided other than leaving in the box and not touching, but that defeats the purpose if you ask me.
To give you an idea here are the shots of both sides, one has lumps in the plastic from a bad mold the other doesn't.
