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.

He had no issues building this & it works! Very cool project for his 1st engine build.

Great build, comes with the motor and every piece came with the box. It took some hours to build but was quite straightforward, having only 2 bags of bricks. Great gift for my dad

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.

This was really neat to watch my son as he tried to navigate putting this together. Quality time together achieved!

Missing parts.... Unclear instructions....

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
