I like stirling engines. Love to see them run. This one is especially interesting because it's so quiet. Just sits on my TV comcast box and just runs and runs. I only gave it 4 stars as gift because I can think of anyone who would want it besides me😊

Was running on top of my hot coffee cup moments after removing it from the packaging.
