I’ve had no issues so far with it. I’ve been on 4 trips with so I’ve aired up about 24 tires between mine and some buddies tires. It has both a cigarette port plug and a basic 2 prong 12v outlet plug. The cigarette plug cord is long enough to reach every tire, the 12v cord is not, an extension...
So far they’ve worked out pretty good. I need to tweak them some more to get them all a little more accurate. My goal is to get them to to all air down to 17psi. After a couple of uses they range from 14-20 but again that’s on me for not setting them correctly the first time I tried to them.
