I like that I can set the desired pressure and switch off the device. It stops when it reaches the desired pressure. Also, the huge battery gives the device amazing performance. I inflated my garden tractor's rear tires from 5psi to 12psi in about 30 seconds, I was blown away! Congratulations on a great product. I have already sold it to my friends so they can buy it for themselves. The device charges fairly quickly, which is good.
