    it’s good,
    pro:1.awesome bluetooth module
    2.sound clarity is good
    3. included trouble and trouble volume
    1. bluetooth is the only audio input (need to install aux)
    2. the case is almost completely sealed so the range of bluetooth and is quality some times is so bad
    3. it needs to install a cooling fan (it would be better and increases it’s life and performance)
    4. at high volume some times we’re adjusting the volume and controls some time it’s stuck (maybe it’s the bad side of the almost sealed box)

    I think my review is helped
    thank you
