When I first looked at this, I thought "man that's cool!" cause I love my gadgets, but I'm struggling to see the value in a grappling hook that you can't use for climbing. Also, the description is a little misleading, because the first sentence says "use this to get your ball out of the tree", but later in the description it says you can't use it for climbing, so I really have no idea how this would aid you in removing something from a tree.
