Query: You Get What You Pay For

This pump barely works. I bought it for automobile tires, but they use the same Schrader valve as many bicycle tires. The pin inside the valve is a cheap plastic piece that barely manages to push the pin in on the tire's valve, so it's hard to get a seal without removing and re-seating the valve repeatedly until the pressure gauge reads above zero. Even then, the seal is often not good, so it's very hard to pump the air. The gauge also reads on the low side, at least at car tire pressures.
