A sure buy at $4.99 (New) Late March 2021. Glad I bought it then as it is currently $6.49 (March 25th). April 2021). ), from $6.99 by then. I don't have a practical way to test accuracy like another very helpful reviewer suggested, but I'm confident that this sensor is just as accurate for the job it was designed for and that it's a classic design acts. It is as easy to read as most other gauges of this type. Hence 5 stars until proven otherwise. This pressure gauge is rated to within 2 psi. My understanding is that these types of gauges are most accurate at and around the midpoint of the scale they use. So for the big ol' 18 inch SUV tires, #120 was the best option, not the one that only fits #60, which is great for tires that inflate to around #35.
