ok but not worth money

Although the product meets perfectly its purpose, but stupid is that you can not issue the light, so you could set up in the bedroom, the device sometimes. Power also quietly whirring sounds.
A minus, but this may be due to the clock itself that these slips always a little back and forth and when it reaches a certain rotational angle out loud clacks down a piece. Slipping grip on the ring around the the clock is wound back and forth.
Conclusion: a lower price would be appropriate. Would I buy it again I would be willing to spend for more than 25-30 EUR.
