On the whole, it's very satisfying. It's beautiful. It works well for my steam engine. The drawback is that the shaft is a little bit large, a little wobbly at high speed, but it's not a big problem. There are holes in the base for easy installation, but it is too close to the shaft for the screws to be lowered.

总的来讲还是很满意的，很漂亮，给我的蒸汽机用效果不错。缺点就是轴的缝隙有点点大，高速转的时候有一点晃动，但是问题不大。底座上有孔，安装蛮方便的，但是距离轴太近，螺丝只能放下面。

This little regulator works well. Fully adjustable so my steam engine RPM is now realistically nice and slow even with the steam valve open fully.
