Unfortunately, I belong to the 8% of people who wake up any easier by the light alarm clock, here, however, the device can not help it.
On the device that bothers me:
1. No radio clock, the digital clock adjusted for the period of one month to about 5 minutes to the rear and must be reset often.
2. The alarm clock is difficult to operate by something small touch fields.
3. If you forget after getting the light at the alarm clock off the lights throughout the day and has no auto-off after eg 1-2 hours
4. No batteries for power failure provided.
5. Radio stations can not be stored.
However, an increase is the pleasant light.
From my side a conditional recommendation for your device
