The 12V power cord and inflation hose are a bit short. They are ok but should be a bit longer especially the inflation hose. The auto shut off at 35psi was used fairly accurately for the first time - within +/- 0.2psi on each of the four wheels, using two different hand gauges to check. (once analogue and once digital). Both cables tuck away inside the device when not in use, and the entire device is small so it doesn't take up too much storage space. Overall excellent value for money.
