I've been using Fedex very heavily at work for the past 20 years, and when delivering to hospitals and academic institutions Fedex is very dependable, and they are doing an incredible job.
Yet, even 20 years ago, all the audio items I got delivered by Fedex were damaged, and ruined... the worst being my CD player, that arrived damaged by Fedex, and when I returned it, they left it by the front door of the seller (against explicit instructions from seller), and it was stolen. I ended up having delivered all audo purchases to my workplace, and there was never a SINGLE hiccup with that. Domestic deliveries - 100% of electronics items arrived damaged.
Their system is massively overloaded. But same is true for every carrier. We ship more stuff than available shipping capacity to carry out the shipping properly. Times are hard on everyone.
Bottom line: whatever you ship, TRIPLE PACKAGE IT.
