Like most all the other reviews, surprisingly this product from Sony (made in Sweden) does not perform well at all, period.Even though I too read the other reviews here before buying, I hoped they were wrong and I went ahead and purchased this item. Don't waste your time.It does work, but it has to be right near the radio source, but even then it gives you static. On top of that, it uses alot of power from your phone battery. Great idea, but Sony needs to go back to the drawing board on this one.
