It's small, it's inexpensive (the price keeps dropping), it works, and I installed it in 10 minutes. It's in my wife's company car, and she loves it.The sound quality is really quite good for running the output through the FM receiver. And I love being able to listen to XM selections on my computer by virtue of an XM subscription.If you want, you can also buy a home adapter so that you can play it through your stereo or home theater. But I've heard tell that you have to get the antenna really close to a window to ensure decent reception. It works fine in a car, though.Me likee.
