Bought this today at my local Hastings, taking it back tomorrow for only one reason... the barrel on the adapter is too long and it doesn't stay firmly connected in the 12V or cigarette lighter socket. I have two cars (Honda Civic, Toyota Prius), and spring blades on the sides of the barrel that are supposed to press against the inside of the socket don't go in far enough and it doesn't maintain a firm connection - I think that's why so many people complain that it blinks off.So Caveat Emptor - it may simply be the luck of the draw if it fits your 12V socket or not... maybe domestic or European cars have deeper sockets. However, I can't drive down the highway holding it in the socket to maintain a connection. The sound is great when it works, but odds are it may not work for you.
