"Why does the display shut off after a few seconds? Is that normal?"

Yes—this saves battery. Default is 3 seconds, but you can extend it to 180 seconds in settings. Instructions included. The pressure stays locked even when the display is off.

"Is this a true pressure regulator, or just an airflow restrictor valve?"

This is a pressure regulator. It maintains your set PSI even during continuous tool use (trigger pull). While some reviews call it a 'flow restrictor,' it regulates outgoing pressure effectively for spray guns, nailers, and inflators.

"Do I need to reset the pressure every time I turn my compressor on and off?"

Yes. When you turn off your compressor, you'll need to re-dial your desired PSI after turning it back on. This ensures accuracy and prevents accidental over-pressure. It takes only seconds to readjust.

"Will this work with my specific air tool? How do I know it's compatible?"

It fits any air tool or hose with 1/4" NPT threading—the industry standard. Works with HVLP spray guns, airbrushes, nailers, tire inflators, and more. If your tool connects to a standard air hose, this will fit.
