Packaging seemed solid enough and indicates that this is Version 1.1. There were no damage or marks to paint or otherwise.

There was no installation manual or warranty documentation included. Also see BYD installation video.

The cabinet seems decently made. External edges are smooth. The access panel (not door) is screwed on with six button head cap screws (also called allen key or hex key bolts).
