If we have 1 day for assembly, how long will it be in transit from the assemblers to the Avalon shipping facilities? If the assemblers are close then they could pick up the assembled product.
They are located in BeiJing China. Arrange shipment is not difficult.
With less than a week to the proclaimed shipment date there is no reason not to show pictures of a PCB or chassis as Avalon's only competitor has done. Unless they don't have a PCB or chassis to show, which is entirely plausible.
I think some of your questions are reasonable.
