Mould King 17006 Bucket Wheel Excavator Building Kits, MOC Building Blocks Set to Build, Gift Toy for Kids Age 8+ /Adult Collections Enthusiasts(4588 Pieces with Motor/APP Remote Control)

This is an absolutely fantastic kit. It is only a fraction of the price of a similar Lego kit. All the parts are fitting easily and perfectly. Of 8 part bags, only bag 2 was kind of sloppily put together. It mostly had parts in wrong color, but otherwise correct, and it had one pin part in incorrect size, so we had to cut it to length, which was not a big deal and accomplished with a kitchen knife. Instructions are clear enough, considering the complexity of the build. My 11 yo son could follow them. It has electronics parts that provide for an impressive variety of movements, although quite slow. A few of those motors rotated in the opposite direction than shown in the manual, but that is fine, because tiny black switches on the control unit allow switching the direction for each one individually, so play with those, if you are not getting the results like in tutorial. The bucket wheel rotation is kind of creaky, which might be because we did not built it well. The whole model took us about a week or two of building most days for an hour or two. My son was super interested throughout, never got tired or bored of it. Overall, I can't say enough good words about this kit.

The fit of the parts is easily on par well Lego. The build is challenging and the cost is much lower than Lego’s sets of a comparable size.

Update to previous review. Despite the terrible instructions and missing pieces I finally managed to cobble this kit together. After notifying seller of missing pieces, the return e-mail said they'd get them right out. Now your average person would have thought that meant a week to 10 days, not almost a month. Fortunately there was nothing critical missing, only cosmetic pieces. I still have missing parts that I found later in the construction, but I've hidden their locations in inconspicuous places. I do admit it is impressive once built and make for a interesting display piece. And yes, it does work, however, if you've seen the video of it running around on the ground, don't believe it. Unless you glue it together it's almost to flimsy to even drive across a smooth floor. This was not a fun build, as it's a tossup as to what was more frustrating, the poor instructions or the missing parts. Was it worth the money, that's subjective. If not for all the problems this could have been a five star rating. Now that it's finished, I'm being charitable to give it three.

Not sure what all the bad reviews are. These are just as good as lego's, if you put them side by side you wouldn't be able to tell the difference. Yes the machine crawls when it's done, have you ever seen one in action? I have bought many mould king sets and never had issues. I always end up with extra pins and never have missing pieces. Instructions are easy to follow. I like how they show you where the wires from motors should go as you build it. Keep up the great work!

Missing parts not allowing me to finish assembly.

Good kit

Don't wanna pay lego prices? Check out these guys, kits are just as good quality and sometimes better pieces. Fun to build and play with. God my order in good time

Overall it's a nice showpiece, but that's really all it should be used for. Every motorized feature is in direct competition with snails, taking minutes to move inches. They also skimped on pins and connectors when designing this thing. As you build it you notice how it's flimsy and not as secure as how Lego does things. There are parts of the crane that if you tug on, it literally rips off. As I was trying to put something back in that fell out, the entire upper structure detached from the lower body.The quality of the parts are second to Lego. I've built sets from other Chinese sellers and this brand is definitely better than all of them.Overall I give it a 3/5. Strongest point being the quality of the pieces, weakest point it being poorly designed and flimsy.
