As someone who has has several K&F Concept products, my personal experience is it's usually a brand that I can trust.Primarily because of the high build quality their products have and in that respect this cage is no different. Especially how this cage is incredibly well made from a super tough black coated aluminium alloy.Something that certainly does provide a good level of protection for my Osmo 360. Yet at the same time it doesn't restrict with the cameras core feature, taking 360 degree pictures and video. Nor does the cage block off any port doors.I also like how the cage has two cold-shoe mounts, one on top and one on the left hand side, so I can easily mount lights or a microphone. Plus there's a magnet at the base, which both holds the Osmo in place super securely, but also works with any compatible external magnetic mount. A base that's also got a 1/4in bush with securing pins, so I can use this cage with any tripod or selfie stick that uses 1/4in bolts.But it does have a couple of annoying issues, such as once installed it makes opening the port doors rather awkward.It also adds a fair bit of weight to a camera that's held like a phone not a DSLR and that's a noticeable weight especially on a selfie stick. Enough extra weight, that if you forget about it, can cause the camera to tip and drop forward when on a selfie stick.Fortunately when that happens the cage does go a good job at protecting the edges of my expensive toy. However, as is standard with all Osmo cages, this cage doesn't protect the twin bulbous lenses during filming. But you do get some basic lens protection for when the camera isn't be used, such as when transporting it.Though it's not the same type of rubber cap that comes with the Osmo and other cages. The one with this cage doesn't cover the whole top, instead it's a rubber strap with two half domes that cover the two lenses. It will even cover lens which have lens transparent lens protectors. But while it's mildly stretchy, it does require some force to fit it, so you do need to be careful not to break the strap.Though you will need to source your own lens protectors, that's because as is standard for most cages, this doesn't include any lens protectors. Something that's highly recommended because the Osmo 360 lenses are not user replaceable. Instead, if they are damaged, the camera will need to be returned to DJI for factory replacement, which can be an expensive process.Also, when do you get some lens protectors you'll do need to check they'll fit through the small gap at the top of this cage. While all the third party lens protectors I have worked fine, if you get a thicker set then this cage won't lock correctly. And on the subject of the cage lock, this one is also very different from other cages.Instead of using a separate small threaded bolt, this ones uses a slide and press button to lock the cage. The big positives of this button approach is there's no chance of losing that tiny bolt (around 3mm in size), something that's really easy to do especially if wearing gloves or have cold hands.Though the downside is that button is way to easy to accidentally press, which will cause the cage to pop open. Fortunately the strong magnetic base does stop the camera from falling out, but it's unsettling when that happens, especially if you have a LED light attached to the top of the cage.But the biggest annoyance is this cage has a bronzy orange power button on the righthand size. So when I fit the camera into the cage that button tends to accidentally turn the camera on. Yet when I want to turn the camera on or off, the cage button isn't that responsive.Overall ? This case has some issues, especially how some features make using the camera tricky. But if you don't mind working around those it's certainly tough and will protect your Osmo.
