Great Set
Very good set and you can build alot of different items.

Great Quality and Functionality at really good price
This product was great, as someone who's always enjoyed lego but not the high price of the official lego, these technic parts not only look very close too the original lego technic parts but function the same, I recommend you give this product a try.

This is a great value product!
I was concerned after reading a few reviews about missing pieces but thought it looked like a great kit for the money. I am actually quite impressed with the quality as it rivals the brand name product in every way. The parts are indistinguishable and top notch. I thought I was missing a piece close to the end of a build section, found I had an extra piece that was very similar (half height vs full ) and realized I had used the full height piece at a step earlier in the build instead of a half height piece. Before I discovered it was me being careless and not Mould King I reached out and had a reply in under a day. I confessed in a reply that I had found the part but one of my motors was binding and wouldn’t power the assembly. I advised the manufacturer and again got a prompt reply and a promise to send out a replacement. Very good costumer service. The build was super satisfying and quite enjoyably challenging. I plan on buying more from Mould King instead of the other recognized brand due to the high quality and excellent value for cost. ... show more

Gift for my 14-year-old grandson
This was a gift for my 14 year-old grandson. It was what he wanted. He liked it very well and he was excited to receive it.

Creative play
With endless possibilities, this is a great starter kit for kids around the age of 5. Paired with another kit would be a perfect bundle for creative learning. The small pieces can be a choking hazard for younger children. Good quality and the connections between the pieces are good quality too. Recommend. ... show more
