This tire inflator is an innovative, impressive achievement. It’s the best tire inflator I’ve ever seen. I had no idea there was a device that would let you dial in a tire pressure number and then pump up your car tire to exactly that pressure — and then turn off automatically. It’s magical, really.

I had a leaky tire for so long, and got tired of PAYING FOR AIR to pump it up. Now? Bye bye, 50-cent gas-station air!

When I looked at the pics of it on Amazon, I thought it was much bigger. That is not the case. This little tire inflator is scarcely larger than a football, so I stow it away in the trunk and always know it’ll be there, ready to go. A quick plug-in of its nice long cable to the car’s cigarette lighter and it springs into action.

Hard to believe a convenience like this costs less than $33. Glad I bought it!
