Works well
After having used this for two months, I would not go back to a standard alarm clock again. The light helps me to gradually awaken in the morning, and helps me not feel so groggy when I do finally get out of bed. As has been mentioned in previous reviews, it is a little complicated to set it (which is why I am not giving 5 stars), but once you figure it out, it really is not that difficult. I love it.
Rating: 4 stars
