My friends and I were taking a road trip down to florida and needed an Fm transmitter that was compatible with all our various audio devices. This item was the perfect answer. I've used a number of fm transmitters before and this was by far the best quality wise (The I-trip is a pice of garbage btw) and i love the fact that it connects directly to the headphone jack. I-river makes quality, practical, and somewhat sexy looking products. This product was easy to use and made my trip that much better. It's worth the extra money for the quality and durability of this product.
