almost all parts have a good or very good quality.
following Parts aren't perfect:
technic pin 1/2 : poor clamping force
1x2 Tile bright yellow: not the same color as the other bright yellow parts
Plate special 2x2 with Groove and Center Stud: too small
the hose 3mm (?) an 22 Studs long is to thin (I will come back to this later.

some less important parts (2 1x3 Tile(white) where missing or damaged (miscast) => I will ask Joy for substitudes (but for now i was able to take equal parts from my collection)

the only thing I was disappointed is the Machine Gun Section (see Photo 2&3)
there are 1x2x1 Bricks with Cross hole supposed to be put on a hose and aligned in a prper way - but that works on the one side just quite good and on the other not at all.

Anyway for the amount of Parts and the building fun of 10 hrs (approx.) its a great model for a good price.

The Design is almost superior. As a fan of the Video Game "Horizon Zero Dawn" I'm absolutly satisfied. The Model looks awsome.

The PDF Instructions a very clear and it's an easy build for experienced user.
