I have the JBL and I can get by very good with reflected light. Even when I'm out at night waiting for the bus the streetlights are very good for reading. Normally, I'd have to bring a headlamp or something. The batteries seem to last about a week to ten days, depending how often I pick up. One of my fav thiings is that I don't get that glare and light bouncing off the screen. It can be blinding.
