I own a dozen or so filters from various manufacturers for my cameras. We all know that when you're looking for a filter, you will see offerings that run the gamut on pricing, and sometimes it's hard to tell the difference between an inexpensive product and one that costs more. The moment I received this filter, I knew it was special. Let's start with the packaging. Instead of being shipped in just a dinky box or plastic bag, this has a sturdy cardboard box with a metallic sheen. The outside is also completely printed with QR codes for info, specifications, etc. On the inside, you get a sturdy, transparent storage case that snaps close. Inside is the filter with a LENS CAP attached, as well as an orange lanyard. As a bonus, you will get a sealed cleaning cloth. I don't think I've ever purchased a filter that came with a cap retention lanyard and a lens cap before. I am using this for my Fuji X100V, and of course, it fits perfectly. I can use the included lens cap with any filter I decide to use. The only con I've found is that once you get this on and rotate clockwise a few times to get the right CPL effect, the threads are really tight. The threads are also so short that it's hard to get a grip on just that area to get them off. I had difficulty removing the filter from my camera and had to resort to a filter wrench. However, this is not unique to just this filter. All filters could have this problem with removal.
