Generic amplifier, different from what's advertised in the image
I received an amplifier which is different from what's shown in the image. The amplifier I received has Bluetooth, AUX and USB as input and transmits BT-BLE-APP when turned on but there is no app that I can use to control the amplifier. I tried all the common amplifier apps like Wuzhi and synlink but nothing worked. I sent multiple communications to both Amazon and the seller but received no response and now I'm stuck with a useless amplifier. Won't recommend this to anyone.
