I bought the Squeeze Box, because I wanted to have a compact internet radio with good sound, which is also easy to use. Here I was also oriented to the previous reviews and did not regret my decision. Within a few minutes I had installed it, the sound is in spite of the small dimensions of very neat. I have therefore not only awarded the fifth star because an internal battery pack is not part of the basic equipment. This I have in the meantime acquired, otherwise in case of power failure, for example, the sender would have to be reprogrammed and the use without power (eg outside) would not be possible.
