Larger than I expected, about 6 inches tall and about 5 inches deep. Have to push the brightness button several times to get the light to turn off, maybe a menu setting to turn off automatically but I can't find it very nice analog looking clock. If it makes noise I can't hear it. No clicking like some clocks do.
Sangean makes great radios but one important feature they lack is backup batteries. This should be standard for any alarm clock in case of power failure.
I had an old analog clock that was making me late for work, I decided to get me a new one. The Sangean RMS RCR-9 is the best I could find to replace it.
