Primarily, it occurred to me on the SD and USB slots, which is to differentiate good and via FB. The CD player is good, the tuner also, only the FM antenna is not sufficient for my own residential area difficult reception situation, but that's been known in advance and can not be blamed on the device. The speaker output is for normal living spaces in terms of volume than adequate and excellent in reproduction quality. The transmitter separation is also absolutely good on the FM band; the MW range I do not use, even though the device is also designed for and supplied with a correspondingly-specific antenna.
As I said, the quality prevails. The only -very vage- Limitation; LIMITATION is that I use the device only for three days; whether restrictions are set after prolonged use, so it can not be assessed here. I trust continues to Kenwood, it's not my first unit of this company.
Addendum: As described, we use two devices of this type and are fully satisfied to date in July 2013 after two and a half years.
