I can only agree with the general euphoria. When manic heavy readers with weak eyesight unfortunately I come quickly reach their limits: in hotels with poor bedside lamp, on summer evenings on the (non-illuminated) and balcony at all in public places or places where there is a lack of light. I have tested the owl at night in bed as the only illumination. The room is of course not as bright as day, but the book is adequately illuminated. Finally, it is the support class. Less than an hour after a request I have already received friendly answer. Everything great!
