I have both Sony covers, with and without the light. While the lighted cover is super convenient for reading at home, I wanted the smaller cover because I read outdoors so much where I'll never need the light and wanted the smaller cover for convenience. So I ended up also getting the
Mighty Flex Travel Light and love it. It's actually brighter than the Sony lighted cover. I clip it on the front flap once it's turned back and snake the neck around so it's actually sideways across the top in the same position the Sony light was. And it only takes 1 AAA battery, I didn't want to deal with special batteries or the weight of needing 3 batteries like larger models require.
