The air compressor is very light and easy to use with LED display and LED light on the side, essential for emergencies. You can set the pressure you want and it will turn off automatically. It comes with pen and blower attachments which are very handy to have in the car as they are so portable. Best of all, it eliminates the need to wrap the battery around a long cable to plug into the car's 12V socket. I'm so glad I have him!
