First of all it be a cordless and very light clock which some people may find useful . its more like something you can travel with vs something you would use in you bedroom . I guess i miss the cordless part in description . because it be cordless the background light do not stay on and at night you can not see the time unless you press on snooze and the light only appear for a few seconds . unless you press on snooze there be no background light and you cant see a thing on this clock . I prefer alarm with background light so it stay on through the day and night and i do not have to press on anything to see the time . secondly , its be over 24 hour and the clock still do not synchronize with time zone and i will have to set it up manually now . it be low price alarm clock and you get what you pay for . I would go for a more expensive alarm of the same brand as they be much better and more solid clock with backup battery install in case the electricity go off and etc. .
