after read the mostly good review for this clock , I go ahead and order it . I be surprise to see it be not anywhere near as large as two VHS tape like one reviewer mention . it actually measure 5-1\/2 '' wide , 3 '' tall and 2 '' deep . it be very lightweight . the one feature that sell I be the configuration of the control . there be a single snooze\/light bar on the top - very simple , nothing else to press or grab accidentally while half asleep - and all the programming button be in the front . only the alarm on\/off switch be located in the back . you have the display option of 12\/24-hour time and fahrenheit\/celsius temperature . the atomic feature be fussy during setup but the bedroom 's location have also be problematic with two previous clock -lrb- a Oregon Scientific and a skyscan -rrb- . I now know to take atomic clock into the kitchen where there be better reception in order to do a initial setup and re-synch twice a year for DST . set up the alarm be fairly intuitive and easy to do -lrb- press mode\/set once and use the up\/down button for the hour , Mode\/Set again , then up\/down button for the minute -rrb- . I be a heavy sleeper but the alarm be loud enough to wake I up . the beeping be polite and not harsh at all . it start out slowly and begin to beep faster the more you delay . from a personal preference , I would have like a blue backlight instead of orange . tap the snooze\/light bar illuminate the display for approximately 3 seconds , which be not long enough if you be try to set the alarm in the dark . I also would have like the time digit to be larger - they be about 3\/4 '' tall . 1\/3rd of the bottom of the display be take up by the date , day and temperature -lrb- about 5\/16 '' tall -rrb- . all in all , for the 6 month I have have this alarm clock I have be happy with it . I have not drop it yet so can not speak to its durability . it do feel cheaply make but if it be anything like a Timex wristwatch , it 'll hopefully take a lickin ' and keep on tickin ' for a few year .
