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!
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!

## Questions & Answers

**Q: The glass piston has a crack.  Can I buy a new piston?**
A: Please contact us though Amazon message system, which is private, and we will mail you a new piston free by USPS. Thank you.

Regards,
Maria

**Q: Does it work on your hand ?**
A: It requires temperature difference of about hot water (~200F) vs room (~70F) so ~130F either way to run great. Assuming your hand is 98F and you are in Minnesota in February (-30F) then it will work just fine ;)

**Q: How do you lubricate it with graphite?**
A: Look for lock/key lubricant.  It is sold at DIY, Hardware, and Stirling engine stores.

**Q: I bought mine about a year ago, but it broke shortly after. The large black heat exchange/piston failed. How can I contact you about a replacement?**
A: CONTACT SELLER OR AMAZON

### ⭐⭐⭐⭐⭐ FLAWLESS! Excited to give this!!
*by K***C on December 10, 2019*

Well two weeks to Xmas I just opened and tested various gifts and several had flaws, so I was very soothed to get to this one and find it is perfectly flawless and seems sturdy enough that assembling, testing, disassembling and reboxing seemed to hold zero risk of anything bending or breaking (unlike so much annoying cheap plastic junk). It is just so nice to see a sturdy, meticulously crafted toy in this era of disposability. And yet, with quality so high, the price is great too! Amazing! I love this because it is a beautifully simple example of concepts that have changed the world. With this you can open a discussion and explain to a kid all sorts of amazing stuff from generators and mills to trains and cars. Experiments can be dreamt up, such as putting various materials between mug and device to compare heat transfer, or trying it outside in the winter cold, using tepid water, to test if it needs heat-heat or just relative heat. Plus it's just plain fun and looks lovely. My only complaint would be that they don't include the graphite lube (and you want that lube! thing squeaks infuriatingly when operated without!). I suppose they don't want the fuss of including a little tube or stick and then handling complaints when it gets squished and makes a mess, I dunno. Or maybe everyone but me already has graphite around the house. It is very useful for applications where oil lube would gunk up with dust. Anyway, definitely add some to your cart with this engine. I found this nice small cheap tube: https://www.amazon.com/gp/aw/d/B07KBT3PDS/ref=cm_cr_arp_mb_bdcrb_top?ie=UTF8
