Article good bill that goes to the essential. The right size cube 9 of 9 cm 6 cm depth light enough to be transported on with a standard AA battery included. It is absolutely inaudible even sticking above the ear. The numbers and hands are slightly phosphorescent. The top button activates a mini light located at the number 3 on the dial for night visibility, it is also used to silence the alarm for 5 minutes before repetitive recovery that lasts 40 minutes. The audible beeper tone is good without being aggressive. Operation very simple old: a wheel button as you pull and turn to set the time and then rotate counter-clockwise to set the alarm time, plus an on / off button for the alarm back. The instruction is in French. Matches exactly what I wanted: an easy to use and good quality alarm clock, article that might seem trivial but difficult to find in traditional shops. Product purchased from Amazon.com and not a third party vendor.
