Similar to the other Leofoto products I've bought, this is a quality piece. It fits and it works. I had bought some cheaper units elsewhere, but that was a mistake because those others were simply not good (one of them didn't lock on), so I eventually ended-up back here and bought the Leofoto unit, and I'm glad I did. Don't waste money on the cheaper units that are out there. Most of them don't have the good quick-disconnect connection. That quick-disconnect is something you'll definitely want. I'd prefer a different shape to the knob on this unit, but once its on the lens I won't need to fuss with the locking knob, so the shape of the knob is not too important. Overall, a very nice unit.
