This product works well and is very practical. In order to make the wire a good length and roll up well, they had to make the wire fairly thin (it's also very tough considering it's fine diameter). So - be warned - if your receptical is close to the steering wheel on the right side, don't leave it plugged in and talk on the left side of your head while turning a corner or you'll get a big surprise! It really does work well in all other cases. Good job, Callet!
