Mould King V8 Engine Building Blocks Sets, MOC Scale Model Kit with Battery and Motor, Collectible Set for Adults, Construction Toys Gifts for Friends Men Teen Youths (535 Pcs)

Grandson built over a few days, one part missing but we did okay. Once built, it is fragile, but secure enough. It does operate but snapped together - it is not meant to be a high precision engine - parts fly off, connections separate. It is a toy that operates.

Absolutely amazing. I am a nerd who like mechanical stuff and as soon as I saw the recommendation of a lego V8 engine, I clicked Buy Now. And boy oh boy I was not disappointed. The quality of each pieces were amazing. However, the instructions were a bit misleading (not enough to not complete it) and I have to go back few steps and redo it again. Apart from that, it looks amazing after completion.

First You should carefully read the directions. It can be very difficult to assemble if you don't. Do not hurry.

Quality of the is great however not perfect . Once build together everything worked fine but one piece was off and that threw off the whole function once it started running. It was easy to assemble however and the design was perfect. For the price this was worth trying.

My nephew loved this. He had a great time putting it together.

Do not order. Pay the little bit extra for Leggo. I bought this as a gift. It had missing parts. After speaking with mould king customer service I was told the missing pieces would be in the mail in a week. I was contacted 10 days later to ask what parts I was missing again. I thought they would already be on the way by then. Amazon fixed this problem for me. Not mould king. Order the brand name leggos.

This is the second time I’ve purchased this brand. I can’t say much about missing pieces because I haven’t been able to progress that far on either kit. There are pieces that just don’t go together; the hex pins specifically. I have trimmed, filed, pushed, pulled and it hurts my hands. A very discouraging, not fun experience.An update: I have since purchased a much larger engine from Mould King. This one is going well and I feel better about the brand. The instructions are a little weird in places and some parts have had to be rearranged. It is useful to have extra parts on hand. I had to replace 2 axles that weren’t long enough for their purpose. I will use this smaller build for parts.

Fun toy that really works! Easy to put together and learn how engines work.
