Way too bright on minimum level. It hurts my eyes in a totally dark room after about 2 minutes.
I'm annoyed because I bought it based on the marketing saying I would be able to "enjoy an incredible reading experience even in the middle of the night.". I took this to mean it would be readable in complete darkness, which for my eyes, it isn't. Well, not without being uncomforable, which kind of defeats the point. If you're listening Kobo: sort out the minimum brightness.
