Looks interesting but I wonder about it's ability to maintain tension over time. I would like to see a review by someone not connected to this product.
For me the lack of a quick release is a deal killer. I keep an L-bracket on my camera for use on my tripod head of choice. I would have to first remove that and then screw my camera to this device.
Just wondering if any good. Sorry for the commercial content.
I bought one a long time ago and some screws fell out of it and now it's worthless, I need to fix it but.... I'm in the market for a used RRS ball head.
