K&F Concept always makes solid gear. I’ve been testing 4–5 different cages for the X5 while searching for the “perfect” one—something lightweight, with quick-release features, GoPro compatibility, at least 2 cold shoes, and solid protection—and this one checks all the boxes.The cage is made from lightweight aluminum but still feels durable. There’s a quick-release latch on top so you can slide the X5 in easily, and if you want extra security, it includes a screw—but you don’t have to use it (which I originally thought based on the stock photos). There are cold shoes on the top and right side, while the left side has a female 1/4" thread so you can mount it sideways on a selfie stick or other rig.It also comes with extra wind foams for cleaner audio and an L-wrench for attaching the included Arca-Swiss plate to the bottom. Once mounted, the cage becomes quick-release compatible—just like the original X5 base (though you may need to supply your own QR plate). Between the built-in mounting options, the flip-out GoPro ears that work without the plate, and the thoughtful design, this cage is ready for almost any setup.Best part? It’s under $40 and often goes on sale—nearly half the price of most other X5 cages out there. With all its features and smart design, this is now my go-to X5 cage. K&F nailed it!
