As advertised. High quality, fits great. The UV lens filter does not show up even in super wide modes. I found out that I have to remove the UV filter after shooting underwater, as there is no way to dry the lens from the remaining droplets. Another observation is that with this cage the camera will drown even mounted on a floating handle. So I would say this cage/case is probably more useful for filming on land, and should rather be removed when on water.
27 days to Slovakia, product looks pretty good, the case is solid and gopro 8 camera sits perfectly in it, I tested it today and I think that everything is fine and I am quite satisfied. The case protects camera perfectly and UV filter covers lens. Now it's possible to use another filter - CPL for example...
