Box was slightly damaged with numerous small puncture holes noted on receipt, but manufacturer had properly packed all prices so no damage upon opening.

Assembly took ~15 minutes; if you can get a helper, 2 sets of hands makes the assembly of the fins much easier as the bases tend to move easily.

The fins themselves are not marked (parts E&F) but if you use the photo ash.  as a simple guide you can easily determine which parts go where.
The paint coverage on the fins is light but that’s logical because they need to be light in order to move easily, so time will tell if the finish lasts…
