DHL in the US: package will be delivered by white windowless van with a crooked magnet on the side. It will be delivered to the wrong house. In the wrong city.
As a German i never expected there to be DHL outside of Germany. Inside of Germany i would say its the best option(fastest(except Amazon) and most reliable, probably 1-2€ more expensive) over ups, dpd, hermes and amazon.
Especially Amazon, we thrown you package on the street, ringed at some random bell in the street and drove away. (But they probably still do more than they are paid for, lol.)
Best thing about DHL is that I can just direct it to a package locker nearby and pick it up from there within a week. None of that being at home when the package arrives garbage, and I get a reason to leave the house and go for a walk.
