As I've both several of these at once I thought it 'd be best if I posted here.
Bought the mark 42, 39 and 7 helmets. The mark 7 seems to be the best of the three. Best finish and paintjob. Although the red on the mark 42 is very impressive as well.
The mark 39 I'm somewhat dissapointed in, as it should not have passed the QC:
Damage on the rear panel
Stain in the paint
The mark 42 also has little cracks in the paint, which you cant really see unless from up close. I'm not sure if this is something to mail them for, or is it within the range of what can be expected? I'm asking as these are my first pieces.
In general I think Imaginarium art did a good job with these pieces. I just got unlucky with the mark 39 (and perhaps the 42), which shows that their QC still has room to improve, but perhaps now that they are part of Prime 1, that might improve.
I'll keep you guys updated on how they handle my claim(s).
