It edits the Exif data well enough. Without the batch edit though, it is only slightly useful, it would be better just to advertise the full $2 dollars because thats what its worth. The GPS location works, but as mentioned elsewhere navigating cant be done by entering a location. You have to scroll to location. But once all of that is done it works just fine.
