It very fun to build. First type of this model I have done. Looks great and engine does turnover with battery motor provided. Looking forward to my next one, it is sports car. Nice assembly instruction book. Very sturdy, parts snap together with procession cuts. Multiple layers to assemble so interesting to build. Pistons and crankshaft turn with ease with battery motor provided.

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!

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

My son is 14 years old and this was an excellent Christmas present; he loved it. I was able to get him away from video games for several hours. It was such a great experience that I bought him a bigger one, and he's still working on it. The product is of good quality, good instructions, nice design, the size was just a little small but ok.

Grandson loved it.

My fiancé loved building this!

I bought this as a gift for my daughter’s friend, and he loved it. Even his dad couldn’t resist—his inner child was definitely happy 😄 I watched the video and was impressed too. Totally recommend buying it.

Amazing, it really works!
