Works Amazing, but overpriced.
This is a great navi tool, but somewhat useless for most people. If you're an outdoors man, afraid to use a GPS by itself, or just want another cool gadget, this is a top-of-the-line navigator. It really isn't too much greater in terms of accuracy or functionality than similar devices 1/2 it's price. My suggestion is to spend a bit less, and use the money on another gadget!
