Awesome gauge
"I'm unsure about the calibration of the gauge, as it disagrees with the gauge on my bike pump, but the gauge is extremely easy to use and measurements seem to be highly repeatable. The bleed valve makes it super easy to overshoot with the pump, and then fine-tune pressure with the gauge. The system hold pressure well enough that if you pop the gauge off your tire and don't release the pressure, you can come back in a week, and the gauge will still read the same pressure."
