iTrip is a cool little device that you plug into the top of your iPod or iPod mini and then tune your radio to a certain station, and the music on your ipod comes through your radio loud and clear! I love having this! This way, I can drive and listen to my iPod and so can everyone else in the car as well! What I like to do is listen to my Ipod using the iTrip, then plug it into my boyfriends and we can listen to his, or listen to someone else's ipod! And you don't have to worry about the annoying, sometimes painful little headphones that never stay in your ears! The only drawback is that it does eat up your iPod's battery alot faster. However you can offset this by just plugging in your ipod to the car charger and then using the iTrip. That way you don't run out of battery and can listen to your iTrip loud and clear for however long your drive is! This is a great device and I love being able to listen to my ipod continuosly instead of switching CDs out all the time! The iTrip is definately worth buying and you will use is all the time! Great product!
