Works just as expected. The plunger does require a bit of force to release the air manually, but it's really a minor nitpick.
Relieve pressure too soon. system never gets to pressure!
After trying a few of these from an order last year, we have been noticing they like to relieve pressure before the pressure switch for FRC pneumatic systems turns off. This means that whenever the system gets close to 120-125psi the RV will open and then the system drops do 110psi and continues to fill. we went back to adjustable RVs this year to avoid that issue.
