I can contribute the following purpose. Yes, the cable is short. But for that very stable. The plug and the cable hit the supplied original Gefriemel Apple hands down. In my application, but just the short cable was good and desired, since the holder is not far from a power outlet in the center console installed next to the handbrake. Navifunktionen This makes them unhappy, but I also do not need, since permanently installed nav.
To shakiness of the plug I have noticed the following. In the cigarette lighter socket, the part was actually to position only with patience so that it loads also. However, the in the socket (12 V socket, not lighter) was very different in the center console of the Fund. The plug is there no less than 2 cm deep in it and has absolutely secure hold. The small overall height and the lateral outgoing cables is moreover no annoying monster out of sight in the vehicle funds, as it was still in my old Nokia car charger. Projects approximately 2 cm from the can. In front were the cigarette more than 4 cm.
In my car (Opel Vectra C) no interference or noise on the radio / audio system are perceptible.
Delivery was fast and the price of just EUR 15, - absolutely justified.
