Being an avid reader before bed, it's the only way I can get to sleep, I've been looking for a good book light for a while. I tried the cheaper Walmart flip up light, but I had to fully open the light for it to stay open and when clipped on the book it would shine directly in my eyes. Not good when trying to fall asleep. I got tired of balancing the light on my chest and aimed toward the book. So I gave this one a try. Although a bit pricey, it's worth every penny to me. Clips to any book and I can direct light perfectly on pages without getting blasted in the eyes. In  pitch darkness light is plenty bright and batteries last pretty long. I also purchased another light for traveling and it packs very well since you can fold it up. I have nothing but good things to say about this light.
