After an exhaustive search for a good FM transmitter, I thought this product was a good choice: it seemed to have a good quality and a reasonable price, but it doesn't work so well after all.The pros:-No batteries needed, just plug it in the cigarette lighter. Also you still have the plug available because of the built-in outlet-Easy-to-read, blue-color backlit screen-Long pigtail cable. To give an idea of how long it is, a person sitting on the rear seat can use the player while connected to the transmitter on the front-You can choose almost any station you want-It can be retracted to take less space when stored-The materials are fine - FM transmitters are not the sturdiest devices anyway, but this one seems fineThe cons:-The worst one: lots of interference and noises. It's hard to find a station where the audio listens properly.Bottom line: Choose a better one if possible. This one is not the worst, but as I said, it's not so good.
