Question: Is this clock cordless?
Document: after a few days the clock shows three hours ahead. i reset it and then the same thing a few days later. what a piece of junk!
Would have given it 5 stars but the alarm wasn't loud enough for me, otherwise a great small alarm clock!
Not what I was expecting. The ad was misleading. It showed the clock  lit. It didn't explain that the light only lit when you hit the button
This is a small, very basic alarm clock -- it doesn't have all of the bells and whistles of bigger models, but it gets the job done. Not that it is NOT a clock radio...as it doesn't have a radio.
This is a fairly small alarm clock. It is perfect for a teen's cluttered room. As long as you are expecting a small clock then this is a wonderful choice. Works as it should.
A good clock, easy to set, the light is really bright. Alarm easy to set and hear! I LOVE IT!! !
Cute little clock. Light works fine and alarm sounds good.If you need a small travel alarm, this is for you. Does a lot for a small clock.
You would think the clock want to see you too with his own flash light...I guess it would be good for those blackouts.It really does get you up in the morning...but just a bit too well.
For a daytime clock that doesn't take up much space, it's good. But if you plan to use it at night, save your money and spend a few more dollars for one that actually performs a worthwhile function.
Sturdy construction. Replaces an older travel clock. Easy to view time and operate. Nice size numbers. May get one or two more to replace other clocks.
Answer: Yes, totally cordless. Clock run only on two AAA batteries. Does not have a 12hr 24hr switch just AM and PM.
