Before I get into the actual review a quick heads up. I ordered the 67mm model for my iPhone 17 Pro Max and that turned out to be a mistake because the larger diameter partially covers the phone’s LiDAR sensor. I’ve attached photos to give visual reference. If you have a 17 Pro or Pro Max I’d order the 58mm version.Now to the review. While this is set is sold as a “kit,” in reality, you are buying a filter and getting a free clip for it. I ordered the ND version. With my “real” cameras I only buy the best ND and CPL filters available – the only kinds of filters anyone needs BTW unless you are shooting in a hurricane, mud pit or desert. For my phone I’m more economical. So, I was surprised this quite affordable filter was built so solidly and had nice performance. To me that makes this “kit” a winner.The filter and clip come in a nice zippered hard storage case, which was unexpected and appreciated. The only problem is the interior of the case is lined with a micro shedding polyester material that collects on the filter. The filter should have its own case or pouch. Ultimately, the hard case is nice, but less useful because of this. You’ll want to by a separate filter case if you don’t already own one or you’ll be dusting off the filter every time you go to use it.The filter’s is aluminum construction and feels solid in-hand. The ND dial turns smoothly for good adjustment ability and properly indicates each gradation. Performance is acceptable with some vignetting especially at ND32. I assumed this would be true when I ordered it because it’s true of every inexpensive ND filter, I’ve every tried. But this one is perfectly usable and the photos and video with it on still better than no filter at all. Color accuracy is good except at the corners when vignetting takes over.The clip is all plastic with a bit of a toy-like feel. Still, it’s practical and does its job. It fit’s on my iPhone 17 Pro Max, even with a case on, fine, though just barely. Because of the phone’s wide “plateau” that extends for nearly the width of the phone I have to angle it a bit so that the phone’s camera lenses are ensconced behind the filter with no light able to peer in. If I clip it on the phone perfectly vertical the filter is cockeyed.Bottomline, this is a nice value for the money as long as you understand the limitations. It provides a good bump up in image quality compared to not using a filter, but also comes with the usual baggage of cheap filters. You’ll likely need to do some editing to lessen or crop out vignetting unless that doesn’t bother you.
