The carrying case is pretty flimsy and doesn't fit all the accessories that come with it without breaking the zip, but the pump does its job perfectly. and I'm glad I bought it. It has an air hose extension coil that goes almost anywhere in your car, near trailers or whatever. It costs a little more than the smaller devices, but it's worth it in my opinion. The end of the hose and extension threads onto the valve stem so you don't have to duck and hold it there while it fills up and it will stop when it reaches your set pressure. I love it.
