Servicing 2 cars this gas generator is used about 3-4 times a year. The fact that the onboard gauge read about 8psi didn't bother me since I have my own high quality gauge. But when the plastic cartridge (the part that attaches to the tire valve) broke after a few months, I suspected the rest wouldn't hold up. I fixed it myself with a metal cartridge. I used it yesterday for the first time in 5 months and now the fuses are blowing. I'm glad I learned at home and not on the go that it's unreliable.
