As a driving instructor I tend to prefer analog gauges, especially as many of them can be calibrated. This was my first experience with a digital pressure gauge. I was skeptical because although designed in the US they are made in China. I have postponed the review until I have had several opportunities to see the performance and accuracy of this sensor, but I am pleased to report that I now trust this sensor and have found it to be not only accurate but consistent is. Everything is fine and I plan to buy a few more for training technicians.
