Bulldozer Technique Building Set, App-Controlled 2.4G RC Bulldozer Truck Construction Vehicle Toys with Engines, DIY Engineering Model Sets for Adults/14+(1508 Pieces)

Wow, you talk about a fun project. This is one fun project. I'm 75 years old and love putting puzzles together. And this is the best puzzle I've ever found in 75 years of my life. I want to give a shout out to the engineers who develop this. You did a superb job on the instructions on how to put this together. I mean, it is perfect great color pictures. You define everything. Well, nice job. I have no idea how you make these 1500. Intricate small pieces that all snap together very well. But it is amazing what you folks done with this matter of fact, I went back and bought another puzzle of a different make. And I'm going to put it together, and I'm going to keep buying them as long as you keep making them

Pretty decent and fun kit. Parts were all there and they fit well. Instructions, for the most part, were decent. A few assembly points had to "studied". The motors worked well. Motor charging point sacks being on the bottom. All in all, great kit!

This was really a good buy.

Only missing one brick, works well. Assembly wasn't difficult, although make sure you carefully study some of the technic pieces at each step as there are few pieces that are a couple that are identical except for say a pin vs axle in one location. Additionally, while nicely packaged some of the parts that should be on bags 1 are found in bag 2 or 3. As usual with these off brand sets, I borrow the wife's baking sheet and open all bags at once after spending 30 minutes looking for said mentioned part in bag 1.

Had 1 piece missing but seller got it shipped without an issue and it came out incredible , definitely might buy from mold king again, remote works great too, and for the price its a good buy

This was a fun build, but the motors to operate the digging device on the back of the unit did not work. The tread motors and the blade lifting motors are fine. There were a few pieces missing which I had to fabricate myself.

My son has been building Lego Technic sets for years. They are great but the price can be prohibitive. Enter Mould King. He was very impressed with this set. It was fun to build, was designed well and is motorized with multiple functions. There were no missing pieces in the kit and had good instructions. While it's a typical model that is not designed to be played with in any rough manner, it has been durable as we've pushed all sorts of things around the floor.

I am still in the building process. Either a part was defective or missing from three different bags. Contacted customer support each time. The first was over the yellow panel. I "robbed" the end pieces from a future bag in hopes that I would get new set before needed. When the same problem arouse with black panel I contacted support again with no response. I adapted the end pieces by notching them to fit panel tab. The third time the items were missing. Contacted support. This is the response: "Due to the large number of pieces in the set you purchased—a complete set of building blocks contains as many as 1,508 pieces—it is possible that some pieces may be missing, （Even Lego sets would be missing pieces.） That is why we offer a free replacement parts service, as well as replacement batteries and remote controls, and we provide a two-year warranty. During this period, if any parts are missing, please contact us at any time. （ Sometimes the missing parts can be found in other bags ） If you still need us to provide replacement parts, please let us know. " Proceed with caution. MouldKing thinks because I moved on building and that I had resolved the problem and did not attempt to send me the right parts. Seeing that there is no inventory list in the manual it is impossible to check the bag for correctness until the part is ready to be assembled. The fact that each of these instances involved modular parts is part of the problem. The third instance could not be fabricated. With out it the build is on hold.
