Bought for mini split test
Perfect for my mini split nitrogen test and saved $ from renting it. I didn't try this hose for the vacuum test but worked well for 200psi line set test.

Works but hard to adjust
I've had it for over a year. It works but the bar to adjust the pressure is very hard to turn especially at higher pressures. I use N2 to test HVAC systems typically at 550 psi - higher pressure I guess than most users. So one star deducted.

It worked, the item was missing the handle to adjust the output pressure. A few trips to the hardware store and I made it work

US specification thread ?
This regulator is for the US market so won’t fit the nitrogen bottles purchased in the UK ,!

Not good
Not for HVAC. Only for welders
