Works Great With iPhone, Moment Wide and case - no X - on Snoppa Atom.
I tried several of these type of variable filters. All exhibited horrible image artifacts, making the footage unusable on wider lenses. There are several VERY expensive ones promising no artifacts. They all have limited range, just like the K&F Concept Fader ND. This one really works. For the higher range, some make you buy another $300+ fader, which I believe consists of one ND polarizer and another clear one. I am cheap, so I put another MRC coated ND, to extend the range. It works great as far as I can tell. I don't have to drag (and field change) multiple ND filters.As far as the size goes, unfortunately, the iPhone image stabilization cause very bad vignetting with the wide lens, so I had to use large diameter fader. I could balance it all on the Snoppa Atom with minimum of counterweights.
