I bought this as a present, and I must say, it is nice. It has a classic old-timey elegance to it, which makes it more interesting to watch as it goes around and around.
This worked great. As engineers we put it through the ringer seeing how fast and long we could make it last by adding some heat sinks and cooling elements. It stood up to the challenge and exceeded our expectations. Great fun classy desk top toy. Great conversation starter, especially in an office full of engineers.
I am very pleased with this device, it is very neat and amazing to watch it spin with either a hot cup of liquid or an ice pack as its fuel supply.
Funny thing, I'm engineer, and I like to play with this kind of models. Thanks !
it's really really nice. it puts a big smile on your face when it starts to spin. thank you for people who made this marvelous device.
