Excellent product, this thing is well made and even comes with some spare parts , I used regular rubbing alcohol as fuel for the burner and it works great.
An awesome Stirling Engine. I just started working from home and wanted something unique for my desk. A great choice. As soon as it came, I grabbed the denatured alcohol and fired it up. Runs great !!!
Works very robustly after about 20 seconds of heating time. Looks well made too.
Was a fun project.The little engine can run well when fired up. Geat mini gift for my husband& my son.
