A bright good quality alarm clock, with good finishes and elegant design. Quite suitable for an adult room, pretty zen. I am very pleased with the product's efficacy to facilitate the early start, although I feel that this diffuse effectiveness diminishes over time. I advise against using it too frequently, for example on weekends.
The absence of batteries is a false problem: who has not, in case, a second alarm clock activated on his telephone, for example, that he is not afraid of blackouts? Especially when important appointment?
