This will sound nitpicky, but for what those cost $499 and $639, I hope the production units show a little more effort, the air vent grilles were hand drilled by a less than skilled person. Wonky and random holes drilled on those 2 grilles shown. Adhesive or caulk around the right air gauge. I know all this has no effect on the performance, but price and attention to detail not fully in sync. So what do the insides look like?
