    In general, not bad. The screen slows down a bit. Budget solution. For low frequencies, of course, a sub is needed. There is no speaker at all in sound somewhere from the 300. It is inconvenient that when setting the equalizer, the sound is interrupted

    Received the item and bench test.
    1. USB, SD and FM source working.
    2. Set correct time stamp.
    3. LCD screen very responsible.

    Though product not performing well due to static noise, i still give credit to seller for having great technical support (2 nights). Looking forward for the replacement unit.

    Found issue with the audio output.
    1. Continous static noise at volume 0.
    2. More static noise as you increase the volume.

    Fault Isoloation
    1. Installed ferrite core with speaker cable.
    2. Reboot the system.
    3. Update firmware.
    4. Tested other speaker 8 ohm, 20 Watts

    So far the issue was still present. This can be power supply issue, pre-amp or amplifier issue.

    Resolution
    1. Seller to send brand new replacement unit.
