This is not a diaphragm regulator. It is a needle valve flow control.
The unit is reasonably well made, but is not a diaphragm type regulator like it says in the description. It is a needle valve flow control device. The digital pressure display is nice and works well. The small size and light weight are a plus and just might be what you need as long as you don't need a spring loaded downstream regulator.
