We got on-time delivery, it came in 3 large boxes that each require two guys to lift.  Really good idea to have two people to set this up, not very easy for one person.  The Youtube videos make it look a lot easier to put together than it really is.  Instructions could have been a lot better too.  That said, all the pieces go together pretty well.  Be prepared to drive a million screws . . . get a good cordless driver for this.  In several places it is easy to make mistakes, so look at every diagram carefully and note that floor and wall panels that look the same out of the box, are not the same, several subtle differences are important.

Pros: Looks like it should be weather proof, but we have not had rain yet.  I plan to silicon seal the floor seams and a few ceiling joins just for added protection. I was surprised by how well the sky-lights and windows work to let in lots of light.
