so simple , yet such a great idea ! finally someone have really think about how people use alarm clock . I love be able to program it and not worry about forget to change it the night before . it be great for odd-time class in grad school and now i use it to get up early twice a week for yoga . good for weekend too . I do not have to remember to shut it off so I can sleep in on Saturdays . and I do not have to remember to turn it on again for Monday . it also look a lot cooler than most of the other clock out there .
