Query: Griffin iTrip Auto FM Transmitter and Auto Charger for iPod (Black)

I can't comment on this particular item from Amazon, simply because I never received it. It was part of a shipment sent via US Mail that according to my local Post Office was not received on the pallet it was supposed to be on. I did receive a refund from Amazon (Thank you), however, I subsequently had to purchase the item from another online vendor at additional cost. The original order (including two other items) never did arrive. Amazon did replace the other missing items as well (Thank you.)at no additional cost.
