I have a classic Captain America Shield from King Arts not the heater shield. The quality is pretty good. Some minor paint imperfections.
I did order the IM2 Arc Reactor with swappable Palladium cartridges. I cannot recommend this as a buy. The wooden box is much nicer than the arc reactor. However, so many issues with defects and quality overall. Starting with the box. Internally all the stops that support the palladium cartridges had all broken off either from shipping or because it wasn't mechanically secured. On the top of the box it looks like a repair was attempted to one of the depressions and is a darker stain vs the other depressions. There was a chip out of the wood base. Now for the Arc Reactor. The website touts a metal reactor and this is all plastic except for the cartridges themselves. The ejection of the cartridges was one of the main reasons I was sold on this, but it sounds like a worn out cd drive. I really felt like this was slightly better than a Hasbro Iron Man toy. The carrier for the arc reactor is also all plastic. The construction is so simple that it makes me wonder why it isn't AL. The box alone is really nice minus the defects and repairs, but alas its just a box for the cartridges so it seems like a big miss when the rest of this replica is not to the same standard of materials. I'm now in the process of returning the IM2 arc reactor + box.
Hope that helps if anybody is looking into buying the IM2 replica.
Ive got the Classic as well and my paint job is really good.
Sorry to hear about the lack of quality on the arc reactor box. Hopefully they improve their QC going forward. I'd rather gamble with King Arts then wait five years for EFX to sneak/release new products.
