clock automatically set to correct time . neat . also very bright led . but it be difficult to turn off alarm in the morning . the large snooze button work , so if you be a person that hit the snooze button 4 time at seven minute interval to turn off a alarm , you will like this product . the small on-off switch be on the back of the clock , in the middle of the other button to set the time . this on-off switch be also hard to move . Acurite customer service confirm my observation and complaint . it be hard to believe that any one who design or engineer this product ever use it . I can not recommend this product as a alarm clock . it would be fine as a large letter , see in the dark , non-alarm clock .
