I have been using mine for about three years and love it. I understand that the regular pressure gauges limit the pressure to about 45 psi. My gauge allows me to use as much pressure as the campground water system offers, balanced by how high I dare to turn it up. My comfort level is 60 psi and no more. This allows me to have great showers with no problems so far with springing leaks in my plumbing. Others may not be comfortable with such high pressure.
As for the gauge itself, I can look inside and see that it physically blocks the water when I turn the screw, so that part is all mechanical. I suppose the dial could fail or give incorrect readings, but I haven't had a problem.
It DOES take some getting used to. If I have it on a system that only provides 30 psi, I will be running it wide open, and I'll need to dial it back down before attaching it to a system that's pumping out 100 psi.
I hope this is helpful to anyone who might be considering the adjustable type.
