Pros: The pump is excellent. First the pressure relief valve opened, but after a few jerks and jerks it stopped happening. I can go from 20psi to 44psi in a minute and 25 seconds on a 275/50 R20 tire.” Bad: Hose and bar mounts are rough. Difficult to twist and turn. The pressure gauge does not work correctly after the pump has been switched off. That's far. And the bag is good, but the zipper is complete nonsense. Very disappointed, the details are not important to either the manufacturer or the seller.
