The ordering process was easy with immediate confirmation and updates at each step until it was delivered - which arrived several days early and well packaged.
The filter itself, and the included hard plastic case seemed of very high quality on first inspection, but it was only when I installed the filter and saw how well it fitted securely on the camera that I could really see the quality of the design and manufacturing.
I've used it many times now and it works exactly as I had hoped it would. The variable ND is just so convenient and makes dialing in the camera settings so fast and repeatable every time.
I have absolutely nothing negative to say about this filter and highly recommend it.
