I got it from 2 days ago, great good quality and easy to install, I must prevent 2 year old niece got it from desk because she was fascinated by it great for work desk decoration wish they included another glass tube in case I break it
It worked great right out of the box and looks great. The instructions were easy to follow. I bought it for my son as a birthday gift. My son like it very much.
I bought this for my 11 year old son but I think it is incredibly cool (I am an engineer). As fuel I used 91% rubbing alcohol (burns clean so does not soot up the toy). I had read a review where the person melted the hot-side tube. I don't know what they were burning but I had no problems with rubbing alcohol. Also I kept the flame smallish so it would not damage anything.We have probably run ours for about an hour so far without any degradation. The stirling engine works well
A minute of heating the glass cylinder and a flick of the wheel and off it went. I expected it to chug, chug, chug like a steam train, but it ran very fast, spinning the wheel and turning the little generator. Very cool. Made of highly polished metal on a solid steel plate with rubber pads under it, this model is very durable and looks fantastic. I really enjoyed watching it run and am very happy with this purchase.
