The sound is very good. But the 6 pre-programmable preset buttons are too vague. Only they do not respond, then you press stop longer and 'ZACK' is reprogrammed station button - press for too long. When press long it takes the previous channel on the current key. Choosing the wireless transmitter is plentiful (but always puts WLAN ahead!), Much better deal than the digital radio. Overall, you can use it well, even if the price (2014: 150, -) is already substantial.
