The Craftersmark portable tire inflator arrived quickly, well packaged and with easy to follow instructions for those with mechanical problems. There are several ways to adjust the hose. Only use a long hose or an extension to reach the unit on the ground when the valve stem is up to avoid having to hold it in your hands. I like being able to use the battery or the included 12V cigarette lighter adapter when the battery is drained from repeated inflation. The digital gauge seems accurate and stopping at the specified psi is also a plus. Having extra tips for blowing up toys is an added bonus that I may or may not use, but it's still nice to have. I have tested this device on several trailer tires, recharged it and showed my wife how to use it. Then I repackaged it and put it in her emergency kit. She is sure that she can and will use it if necessary.
