the pressure gauge is not accurate, I put "60" psi to my bike and it was something like 40 in reality, other than that, the pump is faster than the manual pumps and allows pumping more air because the leg has more strenght than the arm. It's a good purchase because I can avoid going to the gas station to inflate my bike tires every time I want to go biking.
All as described. Shipment arrived very fast :)
