Loved the bag that keeps everything together, wish there was a little pocket for jets inside! All in all a great pump. As stated, inflating each car tire took pretty much exactly 3 minutes. At first I didn't like the idea of connecting small jumper cables to the car tire battery, but I've done both the car battery and the cigarette lighter socket. The place where the car for car tires went both ways took the same amount of time in both directions, and it has a pressure sensor, so you don't need to have a desperate tool. Plastic, although the casing around the metal pump is plastic, but still great! Not a cheap lightweight pump. Inflates inflatables very quickly, I was impressed! The only thing is that after 6 minutes of running I pulled the plug because I was overwhelmed and the fork was a super hit! So don't walk too long. Overall, I really like this pump! Great for going to the lake and blowing floats there. I bet it works on air mattresses and flat tires too.
