Review: Been wanting one for years - happy I waited! ❤️❤️❤️❤️❤️ - This is a terrific gift/contraption/geek toy/objet d'art AND objet de science! I had been wanting a good, relatively inexpensive, low-temp Stirling engine for some time, and, while this isn't low-temp enough to run solely on the heat of the palm of your hand (as some are, or at least *claim* to be), it's perfect as a temperature indicator for hot coffee and the like. It's a great value, well-made, easy to assemble, aesthetically somewhere between steam-punk-chic and a more Art Deco/Bauhaus, chrome-tinged, industrial design, and it works very well! I haven't tried yet any sort of lubrication of the moving parts, so I'm probably not getting maximal operation out of it, time-wise, but I find its gentle squeak endearing, like a tiny component from Chitty Chitty Bang Bang's inner workings. Besides, it runs for quite a few minutes before it slows down enough to let me know my coffee is no longer too hot to drink. If you or a loved one is a fan of science-based gizmos and toys (I hesitate to use that word, because this is so much more than a toy), you will get great satisfaction and pleasure out of this device. Arrived quickly and well-packaged, so no complaints there, either. Five stars!
Review: I would give this machine and this company ten stars if it were an option. - I could probably go on praising this machine and the company that stands behind it for hours. And the machine can and does carry on for hours, pleasantly ticking away atop a mug of tea. But I'll keep it to the pertinent details so you can get on with ordering yourself one and enjoying it as I'm currently enjoying mine. Not only is this machine a work of art, beautifully crafted to show off it's mechanism, it's also a very effective functional demonstration of a centuries old technology. And a fantastic example of a handful of scientific principles. Not to mention a stunning and entrancing conversation piece that's guaranteed to amuse just about anyone. Firstly, the packaging these machines are shipped in is very sturdy. They really care about it getting to you in perfect shape. Second, the machines themselves are very well made. They don't seem to have spared any expense in quality or craftsmanship. Third, and most important, this company really stands behind their product. Customer service correspondence is prompt, attentive, and eager to please. Sure, these engines are really just very elaborate toys. But I have no doubt that mine will last, and continue to bring joy and amusement, for a lifetime. The perfect gift for that person who's hard to shop for. The perfect addition to anyone's collection of curiosities. It's just as much at home on a desk, a mantle, a window sill, or your coffee table. Fair warning: you're going to want to collect more of these engines once you get this one out of the box!

### ⭐⭐⭐⭐⭐ Smooth Running Engine

Very nice! Had to push hard to get the connecting rod to snap onto the shaft, but then smooth sailing. Works nicely. Cranks away for many minutes over a steaming mug.
