The radio had a good sound if it would work smoothly. After all the recommendations (eg, reset, etc.) led by the service hotline to no success, I wanted to return the unit back within the period referred Amazon. Wrong! Reason: Devices containing explosive content can not be returned !!!. She discovered that even with batteries included (the device has a rechargeable battery). Since the device in the specialized shops is no longer available, I assume that the seller was aware of the defect. A lot of money for "nothing"!
