Query: Works surprisingly well!

This transmitter works surprisingly well! I was expecting some static like I've seen with my friends' transmitters, but I hear radio-station quality sound. Can transmit to a large range of frequencies (not just a switch with two or three options) and runs off two AAA batteries. I have mine hidden behind my GPS with only one small wire (not an ugly cable to my cig. lighter), allowing me to output the GPS audio to my car speakers which is very convenient. My GPS has an MP3 player, so I can turn up my music as loud as I want, and the GPS will automatically pause my music to give me clear turn directions. On top of everything it's one of the more reasonably priced FM transmitters, what more can you ask for?
