Having not used something like this before, I am very happy with this type of alarm clock and the way it wakes up with light instead of a harsh beeping. Some reviewers claim they could not get it to work. I understand as it is not intuitive. If you don't have the instructions, you probably won't figure it out on your own. With the instructions, it's not overly difficult and most features are customizable (how long should the light build-up last, what sound should play, etc.) It feels light and kinda cheap, but it works and doesn't cost much. I'm happy with the purchase.
