I picked up a Mighty Brite today for my K2 and Amazon cover (my previous book light did not attach well to the cover). Based on other reviews I had seen on KB that seemed to be the best light. I love it already! It is super-bright and it has two light settings. Both settings do a great job at illuminating the whole screen. I hope you love it too!chocochibi said:I'm glad to hear the Mighty Brite works with the Amazon cover. I just ordered one last night from Barnes and Noble, with member discount I got it for $10.
