A fun, interesting product. This would be a great gift for someone that likes Steampunk design themes.
This was a gift to my uncle who enjoys science and as some would say ‘toys for adults’. He loves it. It’s a good quality product.
Purchased for my teen son who is into steampunk and engineering. Works beautifully and more affordable than most stirling engines. Shipment done in a timely manner.
Cheap price with high value. That is a gadget for entertainment. I can use it to attrack my little boy keep away from ipad
That is a funny engine model toy, even I can use hand to transfer heat to the model and let it work.
