Review on FOVAL Digital Tire Inflator: 250 PSI Pressure Gauge & Compressor Accessories for Accurate Inflation and Easy Connection by Keith Stuckey

This is a good tool. Upon opening the box, I was impressed by the quality of the injection molding. Utilization is even better. It's so nice to have an instrument that pushes, inflates, and deflates as needed, instead of measuring the pressure, deflating, measuring, adding or removing air, measuring again, adding, measuring... but the readings are very repeatable, eh gives me some confidence Another thing I consider an advantage is that the device uses AAA batteries, which are much more readily available and cheaper than the LR44s in my other battery-powered meters. It's also quite durable, surviving an accidental 2m drop test onto concrete. And you have two!
