Mould King Mini V8 Engine Kits That Runs, Build Your Own Visible Car Motor, Physical Science Experiment Models for Teens, Best STEM Toy Gifts for 14+ and Adult 10171 (487 Pcs)

My son loved this gift! He is 12 and put it together easily and had it working in a few hours! It is a really fun project for any kid who loves things like STEM or Lego building!

Very nice and awsome

Great project, wish it had more instructions. Lots of fun to build.

Took about a week to put together, just doing a little bit after work every day. Overall was a fun kit and it was neat seeing it work after it was complete.I only have two gripes. The first one is that instructions are pretty vague. The bags are numbered, but the numbers have absolutely nothing to do with the instructions. Also, once it’s all put together, it can only run for a little bit before the driveshaft comes undone, but that’s a minor thing since it’s just building blocks.I saw other reviews saying that they had missing pieces. Mine didn’t have any missing pieces. In fact I had a few extra. Maybe I missed a step?As far as durability, it’s not the most durable kit, but it’s not bad either. It’s what you would expect from a miniature engine built out of offbrand Legos.So overall, given the price, it was a good kit and I had fun with it, and I would recommend to anyone curious about it.

Bought for grandson. Put together and worked. It is very small but he still had fun putting it together.

Well built, a great learning experience as children learn what they are interested in.

I absolutely LOVED building this and all the parts move as depicted. I display it on my coffee table and everyone thats seen it has turned it on and asked where to get one! I love Amazon! Ill be buying more of these!

When it runs the pullys walk off of the shafts.
