Review: It's legos - It's quite the most fun thing to do only thing is I'm 62 so I'm looking for a 5 year old to help lol
Review: Mould King W16 Engine Kit - I bought the Mould King W16 Engine Kit for my 8 yr old grandson. He's not your regular 8 yr old. He does not watch any TV because his parents do not believe in that distraction. He loves a challenge and this kit is all of that. But this kit is just out of his reach for doing all by himself. He has built a lot of it but he has needed some help along the way. This would have been a project that he could have done by himself at age 11 or possibly at age 10. All in all, he loves that it is a working model that he can take off the shelf to play with from time to time and it does make an excellent display.

*by A***K on October 11, 2025*

Ill start by saying this is really cool..as a car guy my husband and son loves it..and the detail in the motor is so cool But the directions definitely could use some work..some bags had no direction and others seemed to be mixed between bags But over all for the price it didnt take much for my 11 yr old to be able to help and put some together and the details it has is great!
