Rated 1 out of 5 by from Utter rubbish Bought this from Carphone warehouse. Used it first time about a couple of month later went to plug it in and the USB port was loose and broken. Carphone warehouse would do anything as I no longer had the receipt. An utter waste of money on a useless badly put together piece of junk.
