Awesome Train!
AWESOME train! Received all of the pieces. Took 2 afternoons to put together. Used industrial glue to glue some of the little pieces on. Son absolutely loves it! Love that it’s way more affordable than name brand. Pieces aren’t really compatible with name brand, but that’s okay. 5/5 highly recommend. 🌟

BETTER THAN LEGGO
The good... You simply cannot find a realistic cargo train like this in the overpriced leggo city selection. It's simple. Cargo train with truck and crane. Great color scheme. The bad... parts like the rotation of the crane and truck gate don't work well. The crane falls off of you try to turn it. Same with the gate. However, if you have extra bricks you can modify the crane and gate to strengthen. I'll add I picture once it's complete. The mid I made to the crane is excellent. I hope the company sets this post and modifies the design.

Great alternative to Lego trains
This set is a great value for the price. Instructions were clear and easy to follow. Everything was packaged well in a sturdy box that , in my opinion looks better than the other brands. Nothing broken or missing. Better fit and finish than megabloks for sure. The motor and remote are proprietary to mould king and works as it should . The only thing that isn’t as thought out is the crane but does look the part. I’m definitely going to order more sets from mould king and most likely ties with Lego for fit and finish. This isn’t just some cheap knock off, it’s quality.

Absolute GARBAGE
Complete garbage. Had high hopes, but the motor that it comes with is VERY low quality. Runs for maybe 5 min before requiring recharging. Attempted to contact Mould King to have a replacement motor sent. The replacement motor received looked like it had been run over with a car, with the case busted open on one end. Not buying a Mould King product ever again.

Decent substitute
First, my 6 year old loves it. I’m glad. But as the helped to put it together, I had to get the super glue out a couple times because there were groups of pieces that would not stay together. I tried literally 10 times on one part before I brought out the glue. And the instructions aren’t clear in every step. It’ll say put here with an arrow but have the picture turned so you can’t see the location. This is our 3rd mould king and it’s the same issues with the rest of them. But… I can’t afford the Lego brand for these bigger sets, so it’s a decent substitute.
