XtremeMac Airplay Boost FM Transmitter for iPod nano 2G (Silver)

I have spent more money than I can count on FM transmitters for various iPods that I have had. By far, This is the best. Very easy to set up and use. If fact, it came with no instructions--its that easy--plug and play. No downloading of channels on the iPod either. If you have a Nano, you have to have this for your car.

Originally I was going to use this in the car. However, I find I use it more at work and home with other FM radios and receivers. I have had not problems with static (other local station) and I do live in a large metropolitan area (Washington DC). I believe that the static issue a reviewer mentions is more of a receiver issue than the FM Transmitter.
The sound quality is not CD quality, but FM usually isn't. Overall I think its a great little product that actually looks like it belongs to the iPod and works in a car, home, office, hotel, etc.

I have used the iTrip for the past couple of years and while it works great in areas where the selected frequency is clear, it is virtually impossible to change the frequency on the fly when I drive into an area where there is interference... particularly if traffic is thick. The Airplay can be adjusted without interrupting play (as others can) but it also has 3 station presets which I have matched to 3 station presets on my car radio. When I encounter interference (such as when passing through cities on the interstate), I switch between the presets until I find a clear frequency. Why not a 5? The buttons feel cheap... if they hold up over time, it will be a 5.
