K&F Concept make a very good range of camera and photographic accessories, and this lanyard lives up to the company's other high-quality products in terms of construction and materials.It works fine as a phone lanyard - not just for iPhone 17, despite what it says in the product listing. The only downside is that the connector needs to fit into a case, but (as with similar lanyards), it has a tendency to push the aperture for a USBC charging cable out of alignment, making the connection somewhat less than secure. Not a problem though if you charge via MagSafe.I'm honestly not sure under what circumstances you'd use the additional camera connection. I don't have an action camera but I do have a small and quite valuable Panasonic travel camera, which I would hate to lose or drop, and it connects very securely via the screw-fit tripod fitting. But I'm not sure I'd ever walk around with a camera AND a mobile phone dangling round my neck without feeling (and looking) rather silly.But that's just my opinion.The lanyard is excellent value for money and secure - definitely an asset if you want to carry a phone in a busy and possibly threatening environment. But you might want to detach the camera connection before you go out.
