Firstly, an observation: When I fitted the shutter release bar initially - with the Action 6 switched on - pressing the bar gave an error of "Water pressure too high" and I was unable to take any photos or video until restarting the unit. Powering the camera on with the bar / cage fitted cleared the error, although the error was repeatable during the first afternoon of use. I contacted K&F CONCEPT Customer Support to advise them of the issue, in case any other customers found the same. The error has not returned having left the cage & bar on for a couple of days, so I assume the button on the camera has 'relaxed' sufficiently.

The cage is, as expected, a very good, snug, fit on the Action 6, is very easy to put on & remove, with the wrist strap fitted, the kit adds another 192g to the weight of the camera, more than doubling its weight to around 345g. The cage does provide good protection for the Action 6 if dropped and the contoured handle should give some protection to the lens cover should the camera fall on its face from any height.

The release bar slides firmly into the cold shoe of the cage, and provides its own cold shoe for a video light or similar shoe mounted accessory.

The hand grip attaches firmly to the cage body, and is easily removed by squeezing the 2 orange clips on the integrated Quick Release mount. (Orange appears to be the corporate colour for K&F CONCEPT, it appears on every accessory of theirs I have!) In use the hand grip / release bar makes taking photographs with the Action 6 much easier - very little pressure is needed to operate the release and the grip is large enough (although a little deeper would be excellent) to provide good support and stability in use. I suggest using the provided wrist strap (with safety sliding loop) to provide added security to for the camera, as well as keeping it 'handy' for immediate use.

The Action 6 camera will automatically rotate its image to keep the horizon level and in the right place, so using it upside down doesn't need the video or photo to be flipped in Post Processing.

A small caveat... The Action 6 will 'wake up' immediately and take a photo / video if the shoot button is pressed... It is very easy to take a photo unintentially (photo 2) if the release bar is depressed when taking the camera from a bag or pocket...

In my opinion the K&F CONCEPT Metal Street Grip Kit for DJI Osmo Action 6 is a great idea and very practical in use, as well as providing an extra layer of security for the camera if dropped. At its current price of £60 there is an indication that this is a "Premium" product (which is pretty accurate) rather than of inferior construction. As far as photographic accessories go, it isn't expensive, although the value of the item would be entirely the decision of the individual.
