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.

Bought this for son in law for Christmas he loves it. Says it's awes

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.

I’m an 82 year old female who loves Motorsports. Bought as a fun project to stop knitting. It was great fun, a bit challenging but when finished attached controller and Voila,it worked!

I'd give it negative stars, but I can't. Junk from the beginning, missing parts, instructions are terrible and show different things on different pages. Doesn't fit together well and just all around waste of money. DO NOT BUY

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.

Got this for my 11 grandson. He assembled it in an hour with no assistance. Loves it.
