Still, I do not regret my purchase. First, I do not think that other devices do necessarily better in terms of ergonomics, unfortunately. Then it's still very nice to be awaken by light and not by a shrill ringing .. Finally, another nice feature: the twilight mode, to sleep with a light that gradually decrease the duration that is desired, optionally with the music (radio) which also fall slowly. It's also a nice mood lamp, or to read a book before bedtime.
It's just too bad it was so ergonomic flaws for use in the daily newspapers. My advice to the engineers who designed it to contact google engineers or apple to make it more intuitive!
Hint: if you need to change the bulb, any standard light bulb of the same shape should, it will cost you much cheaper than a light bulb of the brand.
