Very happy with their Mill Engine and 16 cylinder Stirling Engine
I recently bought their Mill Engine model and the new version 16 cylinder butane powered Stirling Engine, in two purchases. The transactions went through fine, and even though both purchases were over the Xmas and New Year period, I didn't have to wait to long for delivery to the UK. Both models were perfect, very well engineered, and for anybody tempted to buy a butane Stirling Engine, a standard small butane botle, the sort of thing used to fill lighters, connects fine, no need for non standard adaptors.
