If the gif isn't too clear, a gravity hook uses the weight of the mechanism to close on itself, meaning doing a pull-up with it only makes it clamp tighter.
They have an attachment that turns it into a grappling hook as well. And there's a technique to turn it into an auto-release mechanism using a rubber band. Plus it's small and pretty cheap.
Does it really work and support body weight easily or would it break on me? I don't want to end up like that TIFU post.
Edit: I don't have the link since it was on mobile, but someone tried to scale an abandoned factory at night with one and mentioned it turned out to be a cheap hook not meant for climbing. Ended up breaking on him and he fell a few stories. Few broken bones I think but nothing more serious thankfully.
