The hinge is by far the best design i've ever used. Battery life isn't that great but i usually have mine on a qi charger nearby to rest it on. The only negative, which by the way plagues every foldable on the market currently, is the battery life.
The cursor is often unresponsive backing up a character or two. You're forced to wipe the entire word or sentence. I reset the phone and it works for a little awhile but starts doing the same thing. These phone's are black listed aka- stolen.
