I bought it for my son. It appears identical to the yellow inflator I recently purchased from another company through Revain, but this inflator is $5 cheaper. The battery is easy to charge and allows you to use the inflator without an extension cord. All you have to do is set your desired tire pressure, pull the trigger to start it, and then set it. The inflator turns off when the tire pressure reaches the set value. It easily charges all 4 tires with a spare battery charge.
