In my humble opinion, this is the best accessory anyone needs for the iPod.
I am a long distance lorry driver, and I have had several different variations of this type of thing in the past. The ease of use and practibility of the iTrip is superb.
I travelled the other day from Liverpool to Rugby in convoy with my mate in the lorry behind me, and he could recieve the crisp , clear signal 400 metres behind me.
Anybody who finds a serious fault with this is obviously a musical purist, who would'nt listen to compressed music anyway.
Buy it, it's fantastic!!
