Great kit for engine enthusiasts After spending a fair few hours carefully constructing this kit, it ran great first time! I was a bit dubious about a few of the parts being made of card, but they all function just fine, and there are even a few spare parts in case you make a mistake on one of the critical bits. On its first mug of boiling water, my engine ran at about 90rpm (to start with) for some 20 minutes. I can't imagine finding another working heat engine kit of any kind at this price, let alone one that operates so well. Chris Underwood
Best buy in a decade for an engineer Honestly the best bargin toy i have ever bourght. Usual price for a low temp sterling engine is around £60 for an import from ebay and up to £200 for extreme low temp differance ones. Who cares, this beauty might not work off human heat but it does a good job ontop of a cup of coffee, and for £20 you cant go wrong. It comes with a very good set of instructions on how to build it and also how it functions. This is a first step to designing them yourself. Thanks Grand Illusions! Nick Inoue
