I bought this pressure gauge because I saw it in a YouTube video being used by a professional tire changer. I was impressed by its ability to depressurize when overinflated. And it's accurate, easy to read and it has a locking chuck for me when I bend over and have trouble kneeling, my back hurts from an injury I had many years ago so I have a barometer to stand with and can stand to inflate my tires is a big advantage. The price is amazing and the design of this sensor seems very well built. Of course, only time will tell. But for now I'm very happy with the design and accuracy. I have digital gauges and analog gauges that I've been building for years. This dial gauge is within 1psi of each of them. And the most important of all features is that the cartridge stays on the valve while the tire is being inflated. I'll try the digital meter to see if it works. That way I can keep one in my work truck and one in my wife's car. It's always nice to have them on hand when you need them. I always have a small tire compressor in each of our cars.
