All in all, I find I prefer the simple Comfort Light for the Elipsa
- The screen is outstanding. I often read on it at night, and my reading lamp is a led, but I don't feel like there is blue light, like what hurt my eyes with my first Kobo, the Glo.
- Since when I turn it on, the light is set at 30%, I'm never blinded
- I'm often annoyed with the Comfort Light Pro on the Libra, which I feel is yellowish, even with the "natural light" at the lowest. I exchanged my first Libra after 15 months, because that yellowish had become definitely yellow, but it is still somewhat yellow on the second one - and I know that first thing in the morning I should put a finger on the dented wheel at the left, because the level remains as it was when I turned the Libra off the preceding night, even though the double circle is back at the leftmost position.
