As far as the main function goes, it works great. It is quiet, and the gauge/preset pressure seems to be accuarate.That being said. The preset function doesn't work well for low pressure applications under say 10 psi.Cord length: I found the cord length to be a shorter than i would like. It might struggle to get to the rear tires on a full size truck of you don't have power in the back seat area. Also it makes it tough to air up other things (atv or trailer tires) you have to be pretty close for it to be long enough.Built in light: I see where it could be useful at night. But wish it had an on/off switch. As is, if the unit is plugged in it is on. If you (or one of your kids) were to forget it was plugged in after filling up a bicycle tire or atv tire, you could come out to find your battery dead.
