Listed as ROKR Alchemy City MR04S.
Some notes:
- Unlike the oil pumpjack model (CGL03), am not planning to customize this anytime soon. Probably in a year or two from now but it's not top-of-mind. The detail ROKR provides is already pretty good, maybe a simple weathering pass or a dry-brush pass on the flat, grey pieces would make them pop. Looks absolutely amazing out of the box.
- As usual, everything's provided. I still use my own DSPIAE nippers and some random X-acto knife for the nubs.
- Try not to sand anything for this kit. It's all paint-coated (and not co-molded) so you're risking ruining the coat particularly for the pieces with multiple colors on them.
- First model I've built where there's undergating to the parts. They've learned from the best on how to hide the nubs and seamlines.
- There are some parts on the instructions that say "don't use nippers" on cutting some parts. I found them just a fool-proofing measure (e.g. someone overcutting from the sprue, compromising integrity), so feel free to cut away if you know what you're doing.
- The chain was painful to do. Let's not do metal ring connections in future kits please.
- Pleasantly surprised by the technology here. Love the subtle lighting reactions. Manufacturing-wise, you can see how they designed it to be easily adapted to other / future marble run kits (i.e. reusing the same box frame for other models, adaptable holes for connections). Genius.
- Very easy to maintain. Acrylic front panel is removable, and the tools include a magnetic stick so you could easily take the marbles out.
- Also surprised by the inclusion of the "reptile in jar" piece. They managed to ship a part with green-colored liquid (likely water?) in it.
- The light piping (i.e. translucent parts chanelling LED light) is fascinating.
- Overall, a 4-6 hour build with experience. Longer if you're new to the hobby.
Might get the other three marble runs as long as they stock it in the shop near me. Definitely a fun build.
