The quality of the instructions is extremely high, almost (95%) as good as Lego and vastly better than a lot of the knock-offs out there. The ~1800 plastic pieces were all extremely high quality, too. I found one that had been over-polished (no burrs anywhere on this set, again in contrast to some of the earlier Lego clones). I've never given a five-star review to a non-Lego building block set before. As far as the build, it was tremendous fun. Lego just doesn't offer a set like this, but if you're looking for a set that shows an internal combustion engine works, Mould King offers FOUR, from about $50 to $100. At the end, it worked beautifully after some careful checking (there's one red axle where the motor connects that can get pushed too far into the set and will prevent the pistons from moving properly). There are some fun details: the oil filter, the chain tensioner, and the metal-plated pieces all add to the overall effect. The only downside is that there's probably a better way of building the overhead camshaft. The short axles used introduce a bit too much flex and make it hard for the pieces to push down on the spring-loaded valves. The simplest solution I came up with is to only install one spring on the double-valves (you'll know what I mean when you build it), which is still sufficient to allow the valves to close but makes it easier for the cam to push them open. I won't be deducting a star for that, though. Instead, I'm trying to figure out which Mould King set to buy next... ## Features - The Mould King 10087 direct-coupled four-cylinder gasoline engine (L4) is a common drive choice for SUVs, with four cylinders arranged linearly on a single crankshaft for smooth engine operation. This reduces vibration, and the ignition system ignites the mixture through the spark plug, ensuring stable power output. - Details Shown - Precisely engineered piston and connecting rod assemblies to replicate true dynamics. The details of the internal mechanical structure accurately simulate the valve and ignition system, and the intake and exhaust paths completely correspond to the movement trajectory of the real engine. - Building Fun - 1787Pcs engine building kit can increase your logical thinking skills! You can use your creativity, think logically, and improve your motor skills while having fun assembling a model L4 engine kit. Equipped with XL motor and a 9V battery box(require 6 AA batteries, not include), it will bring you kinetic energy surprise! - STEM Project Choice- DIY engine building kit for boys and girls ages 14 and up. If you are looking for a cool STEM project for your kids or familys. Such as birthday/Christmas/New Year/Easter, etc. This engine model is a good choice. - Professional Service - Engine models are made of high-quality, high-precision materials.
