Great for motorbikes due to its small size but as others have pointed out you don't want to use it for very long especially on a hot day . It works for passenger cars too, but it's "upper", just turning off the TPM light for one tire is enough, but then you'll need to use something bigger for a full puncture on a normal sized tire. You can only let it run for a few minutes, then you need to let it cool down. This works for my bike with smaller tires. The gauge isn't that accurate and the needle vibrates when pumping 5-10psi, but that's enough to tell. Great for small jobs and when you need a small size. Get the high volume version if you want a real inflator.
