Delivered in a box, not particularly good or bad quality container just looks industrial and solid. CGA 580 fitting works fine.

Nice product, shipping through FedEx sucked I’m a 3rd shifter they don’t knock and they need a sign off to receive it. I had to sleep outside in a lawn chair so I wouldn’t miss the delivery.
