I have a 100% failure with #iHateFedEx on international shipments.
EDIT: On anything other than documents.
Would just object, they aren't that bad.
In 2003, I had an international shipment [guitar] that failed. Back then, they gave me my money back (which was close to $1000).
In March 2016, I sent another package internationally and it failed, but was sent back to me. They blamed customs and said I filled out the paperwork wrong. I created an account, resent the package (at $300). It failed. I flew to the destination country to hunt down the package. The people at FedEx would not talk to me, but instead sent me to a city called San Martín. I found out there that it would cost $400 because of storage fees. I paid FedEx.
In December 2016, I sent an extremely important and urgent package internationally. I paid $900. It failed. They blamed me, but I know it's because they made me put details of all 30 items instead of the normal clumping. #ihateFedEx
I am nervous about anything shipped FedEx, except paperwork.
Looks like they might have been a bit optimistic in printing the labels.
