Great quality for the price!  Lightweight, but sturdy construction with two light settings.  I'm also happy with the fact that it uses AAA batteries.  You think that would make it too heavy or awkward but it doesn't.  Its also much easier to find AAA batteries than a lot of book lights that use "watch-like" batteries.  This is one of the best book lights I have ever purchased, I've had it now for 7 months and no signs of early wear or tear.
