Does what it should1/29/2007
If your looking for light weight, not here. It does work and will work inside, many places. Battery life so far (2nd charge) is not to great, but will work when pluggeed into charger also. I wanted to listen to XM on a portable (in US and Canada) and that is what I can do now.
