Query: Works great!

For Christmas I purchased a $20 Kindle light for my husband, which I really liked. I decided to purchase one for myself and found this one for half the price. It's exactly the same, works great, and I can read in bed without turning on the overhead light, etc. It shines on the page very well, I have no trouble seeing, clips on well (although I clip several pages together at once if it's a soft-bound book), and moves easily if you need to flash more light anywhere. So far I've used it nearly every night for about 1.5 months and the little battery is still working fine. It came with 2 spares though, and we purchased an extra package of batteries so I'm good. Although I've read other reviews about the light switch going out, this hasn't happened with mine. At this price, I'm not too concerned about it, either.
