I was tired of paying $1 or more each time I needed air. Not anymore because I have this great little compressor now. Long power cord with cigarette lighter plug. A sports needle and 2 different mattress nozzles. Manual or auto program setting. Press button to select desired air pressure and when the pressure is reached the pump stops. It dont get much better than that.
I am very pleased with this and sure you will be too. Stop paying and start saving. I have shopped with this seller before with good satisfaction in their products and will continue doing so.
