I have owned a Honeywell Atomic alarm clock for many years but the buttons that control the clock have become hard to activate and sometimes the wrong button cancels the alarm setting so it has become unreliable. I ordered a new one because it is a great clock with many good features and it is the only clock with a beep, beep alarm that I have found is loud enough to wake me. It goes through 3 different beep sequences of ever increasing rapidity, each 30 seconds long, then it becomes a rapid fire beep which has never failed to penetrate my hard of hearing ear. The batteries seem to last forever and the time is always exact, The shape of it makes it easy to put in your suitcase.
