The packaging (photo) only partially shows what to expect in it. In addition to a microfiber cloth and some additional information, there is a sturdy, zippered case (photo), which houses the holder, the filter and two thin, rubberized stickers (photo). The holder fits perfectly (here on the 16 Pro Mx), even with my case it seals lightproof (photo). The filter is screwed in and its intensity can then be adjusted by turning the edge (photo). It sits almost directly on the lenses of the cell phone camera - no reflections, no blurring. The first photos weren't sunsets, of course, but light reflections in general have already been perfectly reduced (photo of the microfiber bag in the case) Conclusion Perfect fit (even despite my case) High-quality workmanship (no burrs, precise lettering) Very strong magnet - absolutely nothing wobbles. Easy handling (with the smooth-running dial you can quickly find the right setting) Easy and quick filter change I travel a lot with a 36 MP camera and 200 mm telephoto with various filters. I will now be able to give myself that as a gift from time to time. 5 stars - An absolute “must have” for anyone who wants to do more with their Handycam than selfies.
