Some people say the found flaws. Fo car tires however it struggles. First if you set the PSI you want and hook it to your car tire it will automatically shut down as soon as it starts pumping. IT reads about 41PSI while its filling up the tire. You set it to anything under that and it thinks the tires full and shuts down. Battery life is an issue. I added 10PSI to two tires and it was dead. I have used quite a few of these and this one didn't cut it for me. Any suggestions!
