I first purchased one of these devices for my mother to use on her portch.  It worked so well, I purchased one for myself.  I live in a building with multiple wireless network access points, so I was forced to use the higher frequencies, which limits where I can use the system.  Despite, that I have used it in my office and the bathroom in the moring when I prepare for work. It's wonderful to have such mobility!
