Well I got my Cinch yesterday and got my camera moved off of the default Canon 60D neck strap and over to it. I ordered the big size as I am..well, big (6'4" and not a wafer thin guy).
The materials and build quality are excellent as you would expect from a company that hand crafts everything in Oregon, you can tell it wasn't thrown together in a sweat shop. The large satin finished aluminum buckles and the Cinch pull are very well put together and look awesome. Overall, the basic look of the strap is really nice.
To attach it the main option is to use the tripod mount with a very low profile (much thinner than that other brand out there that likes to use the tripod mount too) and then the left strap mount on the camera. This has the effect of always holding the camera so that the lens is pointed down and into your body with the grip facing outwards. Really awesome as the whole point of this strap is to hold the camera behind you and tightly enough when you have it cinched in it won't swing in front of you if you lean over. Anyone with kids who want to be picked up at a moments notice will really appreciate this. My one complaint is that there is no quick release or swivel anywhere in the strap - you have to use the small "tribuckle" type buckles and tread the nylon webbing straps through the tripod mount and the side strap mount. While this is in theory very secure and not bulky, my problem comes in with the tripod mount. For those rare times I want to use a tripod (I'm not the biggest fan of them), you essentially have to undo the buckle by the tripod mount and unscrew it/reattach it and then rethread the strap. This is because there is no swivel point in the strap - you can't leave it attached to the strap when screwing the tripod mount in as you will have a ton of twists in the strap, and if it is already attached to the left side strap mount you can't just rotate the camera instead of the swivel for the same reason. You can always not use the tripod mount and just use both of the strap mounts on the camera, but that ruins the very useful way it holds the camera and the lens will be sticking out instead of hanging down. I could easily add a snap with a swivel to the left side of the strap where it attaches to the camera's left strap mount, I just wish one that matched the build quality and style of the strap had come with it.
Now, finally, on to the actual operation of the thing. The cinch mechanism is really slick to use. It takes a little bit of figuring out the angle you need to pull at to get the strap to tighten, and you might need to use one hand on the shoulder pad to keep the strap from slipping while tightening it, especially at first when you are getting the hang of it, but once you do you'll realize the huge value in how this thing works. The action to loosen the strap is very smooth and easy. The ability to go from a loose dangling camera to one that is securely placed with the lens pointing down on your back instantly is really liberating. No more camera flailing around at your waist and bumping into everything or flying up when you lean over to pick something up. Cinched down to the smallest size the strap also works as a good neck strap. The neoprene shoulder pad is supple with their Z pattern grippy material on the inside to keep it secure but it also doesn't hold it so tightly that you can't rotate it around your body when pulling the camera up. This strap does not have a gliding element to it like some other straps do since there is now a patent on that design and Luma Labs doesn't want to infringe on it. This does make using the strap with a backpack something of a challenge. You can always use it just as a neck strap, which it does very well at as again it forces the lens to face down all the time. I found that with my fastpack 100 on (empty, with some weight in it I'm sure it wouldn't work quite as well) that I could still use the strap with it slung across my body, I just had to pull on it a bit more to get it to rotate, and obviously the backpack itself got in the way if I wanted to put the camera all the way around to my back. If the strap had sliding connections it would also ruin how it forces the camera into that lens down position tight against your body, so as with everything there is a trade off.
Overall I really like the strap. It looks awesome and the options it provides as far as positioning and securing the camera are really great. The materials and build quality appear to be excellent. It is a vast improvement over the boring and not very comfortable Canon neck strip. I do wish there was a swivel point somewhere in the strap and I may look for some kind of hook with a swivel I can use on the left camera mount to add one to it. Also the challenges with a backpack mean that you'll probably be using it as a really nice neck strap or just over one shoulder if you have a backpack on. The ability to go from a tightly fitting and secure camera to one that is mobile and ready to use and back again with a simple and quick pull is really something that makes carrying around my DSLR and navigating crowds and handling kids a much easier task.
