SOLID AND HEAVY! EXCELLENT ITEM REALLY NEAT!
very well manufactured stirling motor, it works perfectly with a cup of hot water. Great fun fon children and adults
This is 100% as good as it looks in the pictures. Very nice finishing, absolutely no signs of sloppy manufacturing, worked well right out of the box. It squeaked a little, but a couple of quick sprays of WD-40 around the flywheel were enough for it drop to almost no noise at all. Very happy with this purchase.
Nice model working fine on a cup of hot water.
