I opted for this adapter, as I've noticed in other products that they cause harmful interference to radio. Since the Hama brand is also known from other areas and also produces good products, I have gained this small adapter with a clear conscience. My cigarette lighter is located between the handbrake and the gear lever knob, as a car charger for a smartphone or navigation would rather disturbing because the arm requires room for movement when shifting. The adapter is very well made and shows no errors or omissions in, any loose spots or whatever else. He is sitting in my Audi A3 Sportback (BJ 2006) bombproof inside and does not wobble. A loose connection did not exist with me, during charging of the iPod I have turned it invited him anyway. It protrudes only a few millimeters, so that you can still pull it out. Interference when listening to the radio, I have not noticed, I have switched to different channels, running everything clean. So far I'm happy with it, but I could not test with my iPhone 5, a Samsung or a navigation device him. Until then, remain the 5 star, if there are problems, I will change my review.
