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。

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.

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.
