DHL stabbed a forklift through a box and splintered a machine on me one time. The driver dropped it off and ran.
Ups left a $2000 guitar at the wrong house and forged a signature (with help from another driver I got him fired)
Fed-ex left a pachinko on a truck for almost a month and I did not get it til I annoyed a manager so bad he delivered it to me in his personal car.
USPS has done fine with machines (balls on the other hand, not so well) even when in a badly built box with a single loose layer of bubble wrap around the machine.
