- W16 Engine Building Blocks Set, Combustion Engine Model That Runs, Mini Engine Build Kit for Adults with Battery and Motor, Engineering Construction STEM Toy for Teens(952 Pcs)

Fun model and runs. Then the hubs dropped it and it came apart. Unfortunately the instructions were thrown away so it is now a paper weight.

Really good gift for Lego and engineer lovers, usually knock-off Lego sets and cheap engineering sets are low quality but this was really cool and in depth and the engine ran without any problems, the pieces snapped together without any problems, i recommend it for 12+ just cause of how detailed it is and how precise it is but we definitely got our money’s worth

This is very cool, it was interesting to see the different parts, it was easy to build, and worth the price

If you have a teenager that loves to build stuff, this is perfect. My son absolutely loved it. And it kept him bust for hours. The battery powered motor is awesome and taught him how everything works since he had to put it together. It is time consuming but definitely worth it in the end.

Terrible build. Pieces didn’t match up so the build doesn’t function like it is supposed to. Pieces were missing and the instructions are not clear. Not worth your money. The only education you will get from this piece is what not to buy!

This is my first purchase from Mould King - much better price point than some other "brick" sellers. No missing parts. Instructions were clear. Took my time to build this over a couple of weeks and it works! Some tips: the battery description is bit misleading. The manual refers to a lithium battery pack. It's not - 6 standard AAA batteries (not provided) go into a battery box that is unscrewed from the bottom with the provided screwdriver. This is described on the box in very small print if you look for it. Take the time to position and interlock each piece as shown in the diagrams. One small misstep can lead to problems later which requires reassembly. Good fun and recommended!

Kid loved but pieces seemed to be missing

Great to any your kids lego collection. Son enjoyed the build.

War als Weihnachtsgeschenk gedacht und ist vom 9-jährigen Nachwuchs angenommen worden. Wir sind aber immer noch beim Zusammenbauen, aktuell bei ca. 90 % angekommen, manche Teile sind fertigungstechnisch mit kaum sichtbaren aber bei der Montage "fühlbaren" Graten versehen, wo man schon mal kräftiger hinlangen muss. Ich gebe trotzdem 5 Sterne, weil es lehrreich und die Anleitung sogar für den 9 Jährigen verständlich ist. Man braucht aber entsprechende Zeit und Ausdauer, um es zusammen zu bauen.

Gut

Schöner Motor aller funktioniert super für das Geld einwandfrei.

Sehr gute Qualität!
