This filter is made well and comes in a great carrying case. It seems silly that a filter case can be special, but this one is really good. As for the filter, a 16-stop ND is a powerful creative tool, but it's not for the faint of heart. It takes seeing the filter in person and calculating exposures to fully grasp how much 16-stops is in practice. I have had exposures easily reach multiple minutes, and because the exposure is so long, it allows for some unique and creative opportunities. Busy cityscapes can turn into ghost towns, or clouds or water can get extra smooth. One of the ways I want to experiment with this filter is shallow depth of field long exposures. Oftentimes, long exposures are of landscapes with smaller apertures, but since this is a 16-stop ND, lower aperture settings can be used to create a shallower depth of field while still having the characteristics of long exposure photography like smooth skies and water. It opens up a lot of possibilities to push my photography further and it brings back the excitement of experimentation. I just need to make sure to bring something to keep myself busy while I wait for the exposures to finish!
