Pros and cons

Fm station receiver needs to connect to a good antenna to make a clear sound without static.
Fm station save up to 100 station
The remote control can receive 5 meters away
The Mp3 sounds save last track even when repower on
It has an equalizer 5 band in remote accurately
All is works perfectly and plug and play to the amplifier
Bluetooth works as 3 meters, if far, some delay and cut off in sounds
In here where I buy this stuff which is plug and play
