I bought this unit because I need accuracy and reliability and it delivers. It has excellent geometry for checking two-wheeled vehicles and accurately measures high pressure. I spent the required time making sure my van and truck tires were towable and within 1psi of each other. This gauge, dealer gauge and my TPMS show the same pressure. 3 out of 3 can't be too far! Very pleased with the construction and looks of this USA made solid gauge.
