Downloaded it last night. Meh, nowhere near as good as Google/Apple offerings. It would not show me alternate routes to my destination (200 miles away) even though I know there is at least one viable alternate. UI is not very clever, you have to hunt around to figure out how to use it. I'll keep it installed as a backup for when I'm in Europe. It certainly won't be my go to navi app.
