Query: This product is to experimental to be sold

I thought this product would be a great device to add to my daily 4 mile walk. Was I wrong; reception was terrible. I spent most of my time aiming the antenna all over the place, trying to keep it working. The way it was advertised I believed it would truly be portable. It is heavy and awkward with all the wires hanging all over. A company should perfect a product before they release it for sale. We have an XM radio in our SUV and it works on our road. We also get XM online service and its reception is flawless. But this product isn't worth the packaging its wrapped in.
