Annoying is Allerding the beeping when setting the alarm time. I must do, as long as no one sleeps.
In addition, the time can be seen only from an optimal viewing angle. That is in my case, because my bed is somewhat higher than the alarm clock that I have to slightly tilt the clock up to be able to read the time.
The biggest drawback for me is that the off button for the alarm is hidden somewhere behind. You can not blindly get what would be important but in the early morning with swollen eyes fed him. My trick: snoozen First of all, then 5 minutes later (if I'm a bit fitter) exhibit the alarm using another light source behind.
I think for the price you can possibly forget the drawbacks, if you can do without expensive alarm clock on the comfort.
