It is nice not to have to carry so many hex wrenches in my camera bag. I am also happy this tool fits and will tighten the camera hub on my Cotton carrier, and with the carabiner, this handy tool will attach to my straps on the carrier, making it easy to find without digging through the camera bag when I need to detach the camera hub and attach a quick plate, which is now easier with the flat blade on this multi-function tool. So far, so good.
Compact and pocket sized, this little tool handles many different tightening and adjustments needs all in one unit. It is a little pricey, but a very good addition to my camera bag.
