After watching all the videos on the above clip I decided to send off for one as I thought it would be just what I needed. Well it arrived today so I set about attaching it to my rucksack. After much struggling I just about managed to get it on, but I was not impressed with how short the screws were, they certainly were not very secure. I then tried it on 2 other rucksacks with the same problem. Even though I eventually managed to get one to just about hold I found that the Panasonic G6 or my GX7 did not balance well on it and the camera leaned quite a way from my body. I also tried it on the webbing belt of my rucksack. Again too tight, but just about on (this would make it very difficult to move the clip around), but how ever taught I pulled my waist strap the camera always hung at a awkward angle. I think it's really bad that they only provide short screws and then sell the longer ones at a premium price, and I also think that a lot more work needs doing on the design. It was for these reasons that I decided to return it. I still wait in hope for a decent solution to carry my camera and keep it ready when out hiking on the mountains.
