I received the two boxes one day apart. I agree that these are not packed to handle the treatment that a typical ground shipper gives them. My bottom box has a dent. It's small, on the bottom rail, and doesn't interfere with any drawer functions, so I'll deal with it. I would hesitate to recommend anyone else buying a similar deal in the future in light of these experiences.
Regarding the drawer hardware, I'm glad I didn't balk at the lack of ball bearings. They're drawers. They're small enough that I'm not stacking too much weight into any single drawer, and they seem sturdy enough.
I did appreciate that the boxes came assembled. All I had to do was screw in the casters. Every other furniture shipment these days is a real investment of time after delivery.
