The size of the alarm clock is nice with huge display. It's so easy to see the timing when you are waking from your sleep. I also liked the shape of it. I'm also glad that it could be battery operated or USB charging since it's quiet difficuilt to keep up! What can be improved is to have a clear instructions. Eventhough I have setup several clocks, it was a bit hard for me setting up alarms. I can't see the snooze button on top of the clock unless I tapped all over and noticed it. The diagram shows where is what but still they were not clear!
