Nice appearance, but otherwise very mediocre

I've had the wake-up light for a month now, and I'm very happy with it! I don't find the buttons particularly intuitive (it took some getting used to, finding the right button to turn the light off while half asleep while my girlfriend wanted to sleep through the night), but of course, you get used to it after a while. It's nice that you can adjust the light intensity and the time it takes to fade in. The light itself is also warm and pleasant.
