If you're paranoid, this is the radio/flashlight combo for you. It charges by the turning of a crank, like many emergency preparedness items, and the LED seems to burn brightly for quite some time on it. I had the opportunity to test it during a week-long power outage, and it lived up to its "super-bright" name. I didn't use the radio much, but the sound quality is about as good as you'd imagine. However, there is a headphone jack, just in case you're stranded somewhere with headphones and need better sound from your emergency radio.
The lights have two settings, steady and blinking. The blinking can be used as an emergency signal, or to annoy the neighbors.
Don't expect much of a signal from the radio, especially if you live in a concrete building like I do. It seems to work better outside.
