I order this as a birthday gift for my mom . she work over night on the weekend , and she take a clock to wake she up . so , I think , this would be perfect . it work very well , and it be so simple . just pop in a battery , and wait a few seconds , and the time go to the correct time . however , if like I you do not live on the west coast , you will have to follow the instruction for set you time-zone . overall , this be fantastic product .
