The booklight is doing its part to make my marriage go more smoothly. It's bright enough, with both a low and high setting, to illuminate the Kindle screen, but doesn't bother anyone else who might be trying to sleep in bed, instead of read. The base of the light slips easily between the Kindle and the cover, stays put and does its job. It is a bit tricky to turn the light off one-handed, thanks to the dual setting, but that's a small price for me to pay for the convenience. Just make sure you have Triple A batteries to power it.
