I worked great for a week! Radio, CD, Bluetooth all worked good. Then one day while using my phone to stream music it quit. I turned it off then back on and it would come on for a second then the display would go dark and nothing would work. Tried everything. finally I took it back and exchanged it. Hope number two will last longer.?not much bass, with no tone adjustment.underside, the display is hard to read at all angles.
