First off, the box is heavy!  I assembled myself as was too anxious to wait for help.  3 hours.  Mostly prep time in making sure I had everything.  Though the provide a cheap screw driver, a screw gun is recommended.
Everything was VERY WELL labeled.  All holes matched up.  I recommend having a second set of hands to help with final arm assembly (but did on my own). Pay attention to the direction of gasket on final assembly.  I put it in backwards and then had to turn top around which was added work.
Very satisfied with final product.  Solid.  I’m in a tiny home and this has multipurpose use!  I work from home and can put everything away when done for the day.  Haven’t added lights yet and not sure if I’ll need them.
