Review on Effortlessly Inflate Your Tires with the Slime 40020 Tire Top Off Inflator by Samuel Lewis

I have 3 of these, 1 for each machine. I paid about $10 each. Before buying a few, I bug tested one of them. Put it in the freezer and use it frozen, put it in the oven at 200f and use it. In both cases it worked. What really damaged the test unit was inflating to high pressure, don't use it to inflate more than 40 pounds. This is not intended for regular tire inflation. This will take a long time and eventually it will lose its ability to inflate. This is for emergencies and occasional tire changes. It's super small and portable. The sensor sucks. I have one that weighs 20 pounds. Don't rely on the pressure gauge.
