I am very satisfied with this compressor which does not take place and not very noisy. The inflation ferrule can be blocked to prevent air from escaping during inflation. The desired pressure can be programmed and stops when inflate when it is reached. When you plug the nozzle on the valve can be seen in how the bar is the tire and see if it takes a little reinflate if necessary. The cable is long enough to plug it into the cigarette lighter and reach the four wheels. The cable wraps around the compressor for easy storage. The compressor is also equipped with a light bulb for working on his car at night but did not attempt full night I do not know if it lights up very well. I recommend this compressor because a good value.
