I guess at the alarm clock much that he can be operated on light touch, has a large display and is really easy to operate. This can really any use, much better than this rotating things, where you always have to aim for, whether you have taken the correct minutes. And the signal is really long, not as a short drrrrrring and if you have not heard that the eggs cook ever. With other digital alarm clocks I had problems because of the battery, which was a round cell and therefore expensive. Here now fit in well and two ordinary AAA batteries is. So, I am very satisfied.
