Four-star take after a couple weeks with this alloy cage on the Osmo Action 6: it does exactly what I wanted—makes the camera feel “rig-ready” without turning it into a brick—and it’s been painless to live with day to day. The latch is a simple snap, no tools, and the camera clicks in with a satisfying thunk. I can still pop the battery and charge it on the bike rack without stripping the cage off, which is half the reason I use one of these in the first place. The fit around the buttons and doors is clean, and the included silicone lens cap is the kind of tiny accessory I always think I won’t use—then I actually use it.Weight-wise it’s light enough that I don’t notice it once it’s mounted—listed around 80 g—and the little bit of extra mass actually took the buzz out of handlebar footage on a gravel loop the other morning. The EVA pads inside keep the body from chattering against the metal; no squeaks, no wobbles. I ran a mini shotgun on the top shoe and a short selfie stick on the 1/4-20, swapped between them a bunch, and the threads haven’t chewed up. For a new accessory, early buyer scores are high (small sample size, but still), which matches my experience so far.The reason a cage even matters on this camera is the way I use it: the OA6’s built-in mic jack and variable aperture make it way more tempting to rig lights and audio than previous models, so having a cold shoe and a solid thread ready to go is clutch. Being able to keep battery/port access and swap filters without yanking the frame is the other clutch bit—this one gets that right. And crucially, it doesn’t mess with the camera’s waterproofing vibe; I’ve dunked the camera (not the cage) and had zero drama.Couple quirks. The snap-lock felt a tad stiff out of the box—opens fine with one thumb now, but the first day I had to give it a little extra push. The top shoe sits fairly close to the front screen, so chunky shock-mounts crowd the frame; it works, just looks a bit “stacked.” Also, there’s only basic mounting here. If you want locating-pin 1/4-20s or the DJI magnetic connector baked into the cage (for super fast swaps), Tilta’s OA6 cage has that stuff—heavier though, around 0.15 kg. This one lands in a sweet middle: sturdy enough, still nimble.Value is kind of the headline. At roughly £35 in the UK, it undercuts a lot of “big ecosystem” cages while covering the basics I actually use. I’m not seeing a sprawling add-on ecosystem around it yet, but for a lean mic-and-light setup, it’s more than enough.Bottom line: solid 4 stars. It’s a tidy, lightweight cage that lets the you use to action 6 a little better—quick to pop on/off, keeps battery and ports open, gives you a cold shoe and a thread without overcomplicating the rig. I’d love a hair more polish on the latch and an extra locating-point mount up top, but for the cost and the weight, it’s been a keeper. If you want maximum expandability, look at the heavier, feature-rich cages; if you just want protection and the essentials, this one hits that “throw it in the bag and go shoot” sweet spot.
