The K&F CONCEPT Alloy Camera Cage adds an extra 71g to the weight of the Action 6 camera. Fitting the cage is as simple as sliding the camera in and closing the latch, the fit is snug enough to hold the camera firmly with no wobble or slack.Apart from the obvious benefit of having all edges of the camera protected by a very solid feeling cage, the K&F CONCEPT Alloy Camera Cage has raised buttons for power and record, these help by making both buttons easier to operate - the power button is the most impressive as switching the camera on or off is less 'fidgety' than the body only switch, as wel as making the switch between video or photo simpler.A cutout in the cage gives access to the USB C socket for charging or data transfer, so no need to remove the cage for anything but battery replacement, if required.The Osmo Action 6 magnetic QR adaptor has a cutout in the base of the cage, and may be attached to the side of the cage for vertical orientation use.A cold shoe slot is provided at the top of the cage, ideally suited for a small video light, although access to the record button may be a little restricted by short height adaptors.The K&F CONCEPT Alloy Camera Cage is a no-nonsense design that does its job well, in my opinion. This is a virtually instant review, the cage arrived earlier today and I was able to fit it and have a good 'play' whilst out, and a more in-depth assessment when I returned.It is doing its job well, without any obvious hiccups, so rates 5 stars, it "Does what it says on the tin!" (and with no fuss!)
