This is a Stirling Engine that performs. Around 30 seconds of heat and it was moving at full speed. I have been fascinated by Stirling Engines for years and this is not my first engine.

I am an engineering student and needed a working proof of concept for a project and this engine worked perfectly. It held up while running for 2 hours straight. After a while, the wheel did begin to squeak but a drop of oil solved the problem.

5 stars for the engine, 6 stars for customer service. The first one I ordered didn't work. They provide their contact information in the box, my email was answered within 12 hours. A replacement was sent out with priority shipping, and I was told to keep the old one for parts. As a bonus I was told that if I could find out what was wrong with the defective one, they would send me the parts to fix it for free.

Very nice machine. I bought it for a visual aid to use during my Engineering design speech and it was a hit. Metalwork looks very professional and I will enjoy looking at it on my desk from here on out.

Just as advertised! Great quality and workmanship. This is a real un-paid review. Couple of things, first use higher quality isopropyl alcohol 70% is not quite enough. Found 99% is better
