I was looking for a cable for my car that wouldn't fall on the ground when not connected to my phone and it was perfect. It rolls up so it's not always 4 feet long. So when I'm on a phone call in the front seat, the extra cord doesn't go everywhere, but if someone in the back seat needs to use my phone, it can stretch slightly to reach them. The only thing is that if you stretch it too much, the elasticity will decrease a bit. So as long as you don't overuse it, this is the perfect car cable.
