"Zen Only"

Before describing the product, start by defining those to whom it is addressed, something that will not tell you marketing because it necessarily limits the target of the product.
If you're the type and Zen have the chance and the opportunity to live this rhythm throughout your days and you also want to wake up at a certain time, then this is the perfect alarm clock for you. Gentle awakening progressive light, then a very mild natural (birds or waves). So that the tone of your day Zen remains preserved from end to end.
It is clear that in this context the alarm by radio is to forget.

If you are on vacation this works too.

Now if you live in a big city (extreme), and lead and start your day at a frantic pace, and have a tight schedule on waking, so forget this, as in your case it has a major defect and absolutely unacceptable : If it stops at night, everything resets and it loses time because it is not autonomous. And even though it's still quite rare, knowing that the possibility exists will increase your stress "natural", just before sleep ...
You can keep it for the weekend if you insist.

These clarifications made, the alarm clock the size of a small bedside lamp, he is finished, he is touch, his touch is nice and the setting is easy. Its maximum brightness allows trouble to read, and the time display can be reduced to no longer be annoying. Half an hour before the alarm time is gradually illuminates to end up ringing (gentle sound of waves, birds, or Radio) at the selected time.

The wake (up) is really very soft and "natural", and has nothing to do with "the agressivity" sound of a classic alarm clock. It does seem to say anything like that, but in the experience this marks a real difference.

To summarize: Wake finished well at nice design, and interesting concept, but has a major flaw that is not to be radio-controlled, or even just standalone. We exposing a revival in disaster (NonZen so), if a power failure happened overnight.

Personally I lai in the room of my little girl to wake up gently prepares quon time.

PS: The solution if the concept please, is to put your phone alarm clock to ring, say ... 5 'after the time at which you want to get up. And then you can use your Light Awakening peace of mind knowing that even if he were to fail, your phone provides behind. And life is beautiful.
