It is the use that the watch disappoints me. Casio has a uniform user interfaces tradition from one model to another, but this model has some differences that make it difficult to use.
(1) The light goes out when you press another key, then it is not clear set his alarm in the dark. (You must press "light" after every other pressure.)
(2) The portion of 12h to 24h fashion is all too easy, simply by pressing the lower right button. This is ridiculous: most users do not need to make the choice 12/24 once in the life of the watch.
(3) The dual time fashion deprives you of the display the day of the week.
