I looked over just about all the FM transmitters on the site before deciding on this one, mostly because of the featured review at the top. I was a little worried when I got it because it was just in a cheap blister pack and has a very basic, badly translated manual, but all my doubts went away once I tried it out and heard the amazing sound quality for myself.
The last one I had just ran on AAA batteries and you had to put it in just the right spot in the car to get decent sound, but even then it only worked outside the city. I live in Atlanta and there was so much interference that I couldn't use it on any setting without getting tons of static when I was near downtown. I've only been using this a day so far but in all the driving I've done I've never heard the slightest bit of static, and there's even been times when I could hear a radio station pretty clearly with it turned off but could hear the music loud and clear the second I turned it on.
It also has some nice features that allow it to work with pretty much any portable music player, though it's really best if you have an iPod. It has a single cord at the bottom that hooks to the dock port to both charge the iPod and transmit the music, but it can charge and play almost any device. It has a USB connector on the bottom for charging plus a headphone jack and small cable with headphone connectors at both ends, so you can hook one end to this device and the other to the headphone jack on your MP3 player. Because of that I could even hook my Blackberry to it and it would work fine, so there's really a ton of possibilities.
All in all I'm really pleased with it so far, but like I said I've only had it for a day so I'll have to see how long it holds up. I wish it were a little smaller, but that's more because of where my cigarette lighter is in the car than anything else. Even then it has 2 bends between the plug and the unit so you can adjust how it sits, and there are screws you can tighten to lock it in place once you have it where you like it.
