Query: Overall Poor Quality, worthless device

I purchased the iTrip hoping to use it in my car. At first it seemed to work, but I noticed the sound quality was very poor from the start. Even when I placed the iTrip within one meter of my car's antenna, the sound quality did not improve. A bit like trying to tune in an FM station that is just a little too far away to give you a proper signal.I tried changing to different stations to attempt a better signal, but the sound quality was the same or worse. Shortly after trying this, the unit failed completely. Each time I'd reset my iPod the unit would start at normal volume, then get quieter and quieter until at last it was nearly impossible to hear the music unless the radio volume was turned all the way up.I've given up and stopped using the iTrip. I should have known better. I suspected it was junk before I bought it and now I'm out the money I spent on it. Save your money, don't buy the Griffin iTrip.
