I love that I can adjust brightness & screen warmth as it helps massively with my astigmatism. It’s lightweight, durable & really easy to use. I have adverts which to be honest, I don’t pay attention to as they are only visible on start-up that I have noticed. The battery seems to last a lifetime. I didn’t use my kindle for 4 months & it still had 26% battery. If being used heavily, I charge about once per week/fortnight.
