Query: Works great for me :)

I live in New York City and I was a little hesitant about buying XS028 Satellite Radio Power Pod Portable Battery Pack. I was pleasantly surprised with the reception. I use in on the bus and in my office. My office is not near any windows and the reception is very good. I do wish that the battery charge would last a little longer than 3 hours. Overall I am very pleased with this product.
