Bullseye 12V Portable Pressure Gauge Tire inflator Pump - Blue

Fabulous! Removable battery pack to protect the charge as well as easy (future) potential replacement of pack. Easy peasy use. "Girl (and senior %26 disabled) friendly".., ;) ... not awkward, heavy, or convoluted. Instructions clear. No acrobatics to do-it-yourself task. Carrying zippered case is great perk. Slight learning curve trying to lock onto stem, lost 10%23 air the first try ( 8 > ) , but since then have filled rig tires effortlessly, before every trip and checked after sudden and drastic weather shifts. Sorry, Firestone, will miss your friendly faces doing 'free' air check/fill every trip, but safety %26 ease %26 'cool' tires by filling/checking pressures prior to hitting the road is a welcome task. Accommodating the slight loss of air when removing, by setting air fill by an extra 1/2%23. One concern: The plastic lever to lock the hose onto the tire stem, while sturdy, should be made with metal. Otherwise, says what it is and does... and is and does what it says.

Ive used one before but decided that i should speak up that this pump is awesome it works almost as well as it is said to in the ads. I filled 2 1/2 truck tires before the batter ran out you should definately get more of these and advertise them more.
