bought this little guy to keep me company in the gym. very compact and easy to operate. sound is low until you do the research on the web to find that you need to put your location as THE REST OF THE WORLD rather than Europe as the governors of Europe has restricted the volume. or maybe people in Europe just hear better. anyway once that is done the machine produces good sound. been using it for a few hours and the battery is still charged. the only drawback is the FM radio which especially indoors has a ,not so great reception to say the least, and if radio is your preferred source than I would search further for a more powerful reception.
