I bought the clock for my daughter. I was annoyed there, that I had always begging out of bed. In the morning, the mood is often bad, because my daughter and I are real morning person and if I had to wake you up in the morning because they did not stop their normal alarm clock, then the atmosphere was perfect! The Bomb alarm clock has struck like a bomb, they did not want him, but my child is now always awake before the alarm and we both then meet only in the kitchen, so we are both always something cheerful! They like to use the vibrating alert, this part we have slid under the mattress, so virtually vibrates the whole bed. So I'm excited, but turn on the alarm clock in the evening, which one should then not forget (I sneak evening again briefly in her room "control")
