This review is for the 450P-automatic. I have used this once to fill up four trailer tires. Had to use jumper cables to extend the line, since the trailer was connected to my truck at the time. Filled up the tires fairly quickly from 42 to 65 psi. The auto shut off is a nice feature. Every thing in the kit is top notch quality wise. Expect this will last a long, long time. So the price is worth it in my opinion.
