    Second one of this model I purchased; first was about 7 or so years ago for a room I put in ceiling speakers (home gym) and wanted to be able to connect bluetooth for streaming music during working out. Worked great - until a brownout took it out. Basic unit, but all you need if you just want a monitor and bluetooth connection! Well packed, easy interface and good sound!
