I’ve been using this K&F Concept metal cage on my 360 action cam and it’s instantly become a permanent part of the setup. The fit is spot on: the camera snaps in securely with a reassuring click, all the buttons and ports stay accessible, and I can still pop the battery or plug in USB-C without taking the cage off. The aluminium alloy frame feels properly robust with clean machining and no sharp edges, and it gives me far more confidence slinging the camera into a bag or using it in rougher conditions. The extra mounting options are where it really shines – dual cold shoe mounts on top for a mic and small light, plus multiple 1/4" threads and a bottom quick-release/magnetic style interface mean I can move between tripod, selfie stick and clamps very quickly. In use it doesn’t intrude into the 360 image, and the included silicone lens cover is genuinely handy since my original covers don’t fit over the cage. There is a bit of extra weight and bulk, and it won’t fit every tight hard case, but for me the added protection and flexibility are absolutely worth it. Overall it feels like a well-designed bit of “armour” that makes the Osmo 360 more versatile, safer to handle and much easier to rig up for proper shooting and vlogging.
