The compressor is easy to use. It is small and light, convenient for storage. Works great with plug or car cigarette lighter socket. Exact filling pressure set and shown on the display. Good flash lighting. With a shut-off valve, I was able to retread my bike tires pretty quickly. The compressor looks good and is not that loud. The cord is long enough to get the job done. This is especially convenient in that it can be used with two power supplies. That's fair and good. It has multiple valves for other tasks like inflating a ball. This is the best compressor I've found and it's solid.
