I bought this for my monopod so I can tilt my Rebel XTi to 90 deg. quickly if I need to. It is perfect for this purpose. I can move freely along the sideline and get great action shots without having to think about it. I leave the tensioner moderately loose so it remains stable but swings easily. The cast metal frame is robust and I do not expect it will wear out from lots of use. I am very satisfied with this product. It has given me more flexability and allowed me to focus more on what I am doing rather than the equipment I am operating.
