The sound master clock radio is an all-rounder. One can wake you up a USB flash drive or can provide sound during the "resting" of these media, mainly my reason to buy from the radio, a CD or songs (mp3). The sound quality is quite good (a good 3). Unfortunately, the radio stations can not be saved, and there is only one analog tuning. But one can be both an external device, and connect a headset if you do not want to disturb his sleeping partner / partner. All in all, I would buy the device again.
