The alarm clock has been set super fast at the time. The operation is very simple, the alarm tone is pleasant and in the volume as in Interwall rising, the lighting is very good and easy to read by the light dial and the well-tuned color pointer. No tick disrupts sleep. Only the plastic housing makes a somewhat cheap impression, reducing the rating to one star. If you do not like a clock radio and an analog radio alarm clock looking and also do not want to constantly change batteries I can strongly recommend the Quantys alarm clock.
