Very disappointed - probably going to return
Very disappointed. Firstly it looks very easy for the internal plunger to settle out of alignment and allow permanent leakage/bypass. The biggest problem is that both the adjustment cap and the part with the graduated scale are both free to move independently - turning the adjustment knob also turns the graduated scale so the cap arrow points to 2 all the time. Probably about to return.

Poor design
Dial with numbers on should be fixed to the body of the valve and the red knob should rotate around it. In the version I received the two rotated together making it useless. Returned to Amazon and I'm now trying an alternative manufacturer.
