I have received several ED models without problems. I find in the US customs inspections can be more of a problem than shippers or packaging. The packaging of the ED Kingtiger was excellent.
Thick foam sheets and a heavy card board box. EMS is an excellent shipper; but I have had antiques damaged in transit from Japan.
Drop anything hard enough and no matter how well packaged it will bend or break. I had products being damaged in shipments by air and I packed a digital shock gauge with the product and it registered a 100 G impact when the aircraft landed!
