This pump is great! Such a good idea and very well executed. It's the perfect size - so compact that it fits comfortably in my tote bag and tucks neatly under my suitcase, in the perfect spot where it's easy to reach (at home or on the go) and doesn't take up space. The long cable is convenient and workable in my three-row SUV. And it's totally practical. It saves money (and time!) from a trip to the gas station to get my tires inflated, and it's always with me in an emergency! Good product!
