Review on Effortlessly Inflate Your Tires with the Slime 40020 Tire Top Off Inflator by Stephen Chowdary

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.
