Summary: My old (about 4 years) finally had the screen get too dim to use in sunlight even at its highest setting, BUT I love the way it works and looks so I found an exact replacement and copied all my favorites to it.
Summary: Bought this for my wife quite some time ago. It's been working without any issues. I've seen complaints about the proprietary power adapter which doesn't pose an issue for us. It does seem to change the directions to the same location once in a while. we don't know based on what.
