Query: THE WORST book light I've used

This one is a stinker! IT doesn't light the entire page, so you have to keep moving the light from the top of the page to the bottom. This was when reading a small paperback. It would be worse with a large hardcover book! It also doesn't stay put on the book. It uses 3 little cell batteries. The battery cover disappeared right away after I bought it (poor design...I didn't take it off...it popped off and I didn't noticed till it was too late to find it!) The battery didn't last long. The design is kind of cute, but the logistics make it not worth the price. Avoid this one! I borrowed my daughter's "My Light," and have been using it for weeks on the same 2 batteries. It also lights the entire page and it has a great little swivel head so you can just point the light where you need it. (from one page to the next). Try that one instead!My Light - LED Task / Reading Clip Light - Green
