So actually, it is better to follow the instructions to understand how to program the radio frequencies. But otherwise it is no more complicated than that. The sound is okay for a device of this type and function is asked: clock radio. Obviously this is not the quality of a stereo but it's understandable. For the radio alarm, simply turn off the power on the frequency and the desired volume. With the "snooze" button, the alarm will ring again after 9 min (you can not change the weather). Possibility of batteries. Only drawback: the small beings buttons and side by side, not easy in the dark to press the desired one ... Conclusion: very decent for the price. Remains to be seen longevity ....
