I recently went to Autozone and asked for a Milton tire gauge. They not only did not sell them, they had never heard of them. I reluctantly spent $17 on one of Autozone's company gauges. Upon checking my tractor tires that evening it broke. I returned it and ordered this Milton gauge. I have used Milton gauges for years and have been highly satisfied. Even though Milton's are twice as expensive as the general store bought gauges, they seem to me to be worth it. The user should oil the gauge sparingly once every three months - 3 drops will do.
