Works fine, bright enough, lightweight.  Got this for portability and for my kids to use.  First LED book light I've owned and was worried I wouldn't like the 'cold' color of the light as I'm used to the warm incandescent light of my "Itty Bitty".  While I still like the Itty Bitty better, I got used to the LED light just fine.  The bigger issue is that while lightweight, it is still slightly top heavy, and the clamp is not strong enough to prevent the light from occasionally leaning side to side as you move the book around while reading.  Not a deal-killer, but it would be better if the clamp was longer and maybe had a rubber tip or surface so as to grip the book a little better.  Overall, however, based on the other choices out there I think this is a good value.  Recommended.
