Very small it fits in the palm of the hand (5 or 6 cm in dimension). Strong sounds (two times stronger than my BlackBerry rule to bottom). Very easy to adjust: a button to adjust the time, and both are used push buttons on the sides to increase hours / minutes. The same button on the second position to adjust the alarm time. The first button is: show time, reset the alarm, adjust the hour. The second control button alarm: not active, active as possible without Snoozing and with active Snoozing possible. The snoozing is the big blue button that pushing 10 or 15 minutes the alarm. The last button toggles between 12 hours and 24 hours. A small flap moves down to discover buttons, and enter the adjustment buttons. This panel slides back to form a foot wake. Really great for travel. On the rule, is closed, and just ask the close. The flap protects the buttons, so in a bag sleeping impossible to disable the alarm by mistake. Uses two batteries LR44 (do not touch them with your fingers when installing them because the conductivity Skin reduced their load ...). The display is a liquid crystal, black gray, but with a high contrast, time is 1 cm high and 3 cm wide. The fact that it runs on battery that in case of power failure, do not worry ... I win when I do not sleep at home.
