Input:
Bought this radio after several tornadoes had hit our area and we now have a small child at home to worry about.  We cannot always hear the local sirens in the house so we wanted something that would make some noise and wake us up, if necessary.

The battery life leaves a lot to be desired, but there is an a/c jack in the side of the unit.  Unfortunately, it's 7.5volts, which is a little hard to find these days.  I went to Radio Shack and bought an a/c adapter for about $20 and had to get one with a customizable voltage and a separate connection.  Just bring it into the store and they set one up for you.

 It's been very useful b/c the unit was programmed with the SAME codes and our power had gone off.  At least we knew we were under a severe thunderstorm warning along with a tornado watch.  Just having that information made it worth the $20 or so I'd paid for the unit.

I would recommend also purchasing a TV radio with a weather radio since the NOAA announcements don't always give the path of the storm.  At least you can hear the local news tell you which towns are going to be hit next on the storm's path.

Because of the battery life and the cost of the a/c adapter, I'm considering purchasing the docking version of this to keep for another level of the house.  For $45, it seems to be a better deal.
