Although portable, it is already a beautiful diameter, quite satisfactory. It creates a small soft light. My daughter goes to sleep, fixing on her bedside. It sets the desired alarm time, or rather, the time to reach patiently in her room with her stuffed animals or small books before having the right to come wake the parents! At night, it lights, it turns on "sleeping sheep." Two possible positions: clock with little noises or single light will switch as "awake sheep". We preferred, in order that our daughter sleep until then and beyond ... um In the morning, it is turned off, (it preserves the battery), it keeps its setting. Good buy here well relieves parents when children play the game
