When I received the inflator, it read high (40 psi vice 37 psi). With a quick email exchange with the manufacturer, they sent me an overhaul kit, which corrected the issue in about 5 minutes with just a screw driver. When I had this same problem with a cheap inflator, exchanging it (no parts available!) just yielded another in accurate guage.I am now very pleased with this tire inflator. And hurray for companies that have parts available!
