I originally had an adapter for my tape player, but when my tape player broke I was stuck listening to the radio. Then I remembered these FM transmitters and started to look around. I decided between this and one that was cheaper but only had a few preset stations. I decided to drop more money on this just for the security of knowing I could tune it to every station (and more) that my car can.The sound quality is excellent. Only if I turn it up quite loud can I hear any background fuzz. From all of the reviews I was expecting to hear fuzz almost all of the time but this thing works almost as good as my tape adapter(maybe just as good because I can hardly remember the quality of my tape adapter because it has been so long since I used it). Even if there is a station that is coming in quite clear on the current channel it still plays fine. It has happened before that I traveled a long distance to school and when I unplugged the FM transmitter to find that there was a station paying on that same frequency and I hadn't noticed a thing.Anyway, I wish I had more to write but it is a pretty simple device and does what it is meant to do and does it very well. I besides less than perfect sound this is a perfect device of it's kind. I would definitely recommend it.
