Query: It's not fast but it works

I've had one of these for a few years now and just replaced it after it was stolen from my car.It's come in very handy over the years and it never once failed.It has a quick connect/release connector so you don't lose much air when you are attaching or releasing the nozzle. The built in gauge is very convenient as you can see how much pressure is in the tire while it's being inflated.The emergency light may come in handy if you're inflating the tire in the dark or if you're stranded.The only drawback may be the speed at which it fills up the tire.Even in my sedan it took about 300 seconds per tire to fill it from a pressure of less than 10 pounds to over 30 pounds.
