so the first off, the unit should be cleaned and inspected before use. pay particular attention to the treads and mating surfaces of everything. burrs and manufacturing remnants can be present. the gauge is at best about +/- 15% at 125psi. the filter does catch stuff so stay on top of the cleaning of the chamber.for the price its a decent deal.
