"It works but..."
You better buy a car stereo with a line in audio jack, thats quality, this is not enough, lacks on sound quality...

"Quick battery use, average signal"
This works. Bottom line. But battery is drained quickly and the signal fades sometimes as well.

I would suggest this as an entry level item.

"your own music everywhere a radio is not far!"
Works great! You have to keep in mind that first you screw off your antenna in order to improve the transmitting quality (no other radio frequencies will be received, that could disturb listening to your music). Second: give the transmitter a few seconds to arrange radio frequency. Then it will work out in a perfect way and the Ipod has enough power to operate the transmitter for some hours.
Great!

"Kensington Digital FM radio/transmitter for iPods"
The transmitter was exactly what I needed. It works very well with my iPod which allows me to listen to FM stations on my iPod. I had checked every local store and even purchased what I was told would work only to discover it did not. So I was very hesitant to purcahse this online. But I am a pleased customer. It was delivered in a matter of days. Thank you.

"This one actually works!"
After a previously bad experience with another FM transmitter, I looked around Amazon, read more reviews, and decided to try this one. Whatdyaknow, I finally found a decent FM transmitter!

In the city, with all the overhead wires, big buildings, radio broadcasting, etc., there's plenty to overwhelm the airways and make finding a good empty FM station hard. This little gadget is powerful enough to work even on stations that have a bit of bleed-through. Reception is great, static is minimal and easily ignored, and it's small enough to make transporting and using it very easy.

It does have a couple or three downsides that stop me from giving it five stars. It feeds off the iPod's battery, for one, which, for short trips isn't much of a problem, but for long ones it could end up being bothersome. It plugs in to the place where the iPod charges up, so you can't charge the iPod and use this at the same time. Lastly, while reception is pretty good, the best reception tends to be on a direct line of site path to the car radio, and unless you've got a passenger with you to hold up the iPod -- or you're just that good driving one handed -- you have to settle for a bit less than stellar reception and toss the iPod on the seat next to you, or in the ashtray, or in the change well, or wherever else the iPod might be in a sorta-kinda stable position for broadcasting.

Still, I can live with those three downsides because I tend to use this for fifteen to thirty minute trips. If I have to make trips longer than that, my opinion of this may fall. But for now I'm pretty happy with it and I'd recommend it to anyone else in the city who's looking for a good FM transmitter.
