This is a great item for the money...I set it on my coffee cup almost every morning just to watch it work. Everyone that comes into my office is intrigued with how it works. One friend of mine who has cancer liked it so much that I gave it to him and he now puts it on his coffee cup every morning. Still trying to decide whether to get another one like it or a different one...they are all fun and interesting!!

This is a good running LTD Stirling engine. Installed the flywheel and had it running on a cup of hot water in just a few minutes.
