Not good but not bad either
This is not a bad kit at all, especially considering the price and the fact that there’s very little else like it. The packaging and instruction quality are familiar—somewhat similar, for the most part, to LEGO builds. There are some novel pieces, some very cool, that allow for interesting new build techniques. However, some seemingly incomplete blocks are left for you to assemble just to pad the block count—odd and frustrating, especially when they don’t fit together well. I ran into that a few times.Going back to instruction quality—there are several questionable and outright confusing build steps. I’ve built a lot of models, including a few with upwards of 10,000 pieces, and this is the first time I’ve had to use glue to make the build work. Maybe it’s just how my particular pieces fit, but after 30 minutes of trying, there was no way I was going to succeed in a specific step without glue.Most disappointing was that the engine simply didn’t function as it should have. I suspected this all along—the cylinders kept catching early in the build. I adjusted all the rods and checked fittings, but no matter what I did, it would still catch. It rotated manually a few cycles but would eventually seize—either due to the gears themselves, the cylinder housing, or the gear shaft. The list goes on. I pressed on, but it got worse when I attached the electric motor—the build spontaneously deconstructed one of the cylinder heads. Never mind that this particular one had never caught before. I packed it up to be returned, feeling really disappointed about the six or so hours I wasted.All in all, it’s an easy and straightforward build. All the parts were present and packaged properly. But the instructions and finicky construction leave a lot to be desired. I don’t think I’ll be buying Mould King again.

Makes a great gift!
Gave this as a gift. The recipient was blown away by how authentic it was. He’s having a great time working on it.

Doesn't work.
Doesn't work, even after putting it together twice, the pistons keep getting stuck and detaching.

No parts list telling you how Many parts you need for a set of instructions
It's a nice concept but, the parts for the initial build are missing and it's way too expensive a kit to not have a parts list with how many total parts are in the kit so, the customer can tell immediately if they have everything. There are multiple bags with numbers that don't match the instruction books needed parts. Very confusing!

Missing parts
I was missing 2 pieces from the very first bag. I sent an email to the manufacturer, no response. I could not get Amazon to respond either. I have ended up having to order another one. Eat the expense!!

Missing pieces
Towards the end of bag 1 on step 123 I wasn’t given the correct amount to complete it and it will not go together without the piece
