Query: Maximo MP3 Charger/Transmitter

It works great for me! The only hard part is finding a radio frequency that's not being used in major metropolitan areas. I drove 2000 miles and had to change the 'station' only a few times to listen to my book, but that wasn't as bad as having to find a radio station to listen to! Not having to worry about batteries is a boon. A great product...I'd recommend it!
