Now that I have tried 3 different clock radio I am now landed in this. I can only see positives. It was particularly important to me that I hear humming nothing at night. Although the adapter is installed you can hear him humming only within ear contact. The operation works without the aid of the instructions and that's good. The upper keys would only better (in color) can be marked. 2 alarms and a proportionate good radio reception round off the judgment. A very good value for money.
