Smart-looking in a chrome-effect finish, the Airchecker had individual preset limits in 2psi increments from 26-42psi – more than enough for car use. But with a loss of 4psi, the yellow segment was barely visible. Even at 8psi, it was hard to make out the red section; this should have been easy to see, even from a distance. Not that effective, and pricey compared with the similar Bike It.
