The VIAIR generally works as advertised. It will take truck tires to 80 psi quickly. However, there are threee problems that should not exist with a quality unit. First, the fittings for the attachments slip off too easily while inflating (very annoying). Second, the guage does not provide proper readings when filling (it tends to read about 5 psi low), which requires a second guage to check the pressure. Third, there should be an alternative power source (AC) that would eliminate starting the vehicle's engine. That said, this is a compact and convenient unit for RVers.
