I bought this engine for my kid's science fair project.
It was a complete success, the machine performed as advertised.
It's so funny to assembly this stirling engine kit with my 7 years old boy, He is so happy about this
Product was shipped quick and was as described. This little engine is a cool thing to help explain a steam engine to my kids. Plus it's just cool to watch work. Awesome.
This product arrived with all of the parts. And I installed it about 15 minutes. Great!
Bought this and a few other items for a presentation at an underprivileged school. Kids loved it! Excellent conversation gadget. Precision made and be gentle with handling.
