I got this set for my iPhone 17 Pro Max, and it delivers a noticeable upgrade for both photo and video work. The magnetic mounting system connects firmly and lines up accurately with the cameras, making it easy to attach and swap filters without slowing down a shoot. With an ND range from ND2 to ND32, it gives solid control over exposure in bright daylight and helps keep shutter speeds where they should be. One thing to know up front: it is not case friendly. To get a proper seal and alignment, I have to remove my phone case every time I use it. That’s not a deal-breaker, but it does add a step and makes the phone feel more vulnerable while shooting. If you rely on a rugged case or hate taking your case off, this is worth considering before buying. Performance-wise, the results are impressive. Highlights are more controlled, skies hold their colour, and I’m seeing smoother motion blur in video instead of harsh, overexposed frames. The variable ring turns smoothly with just enough resistance, so it stays locked at the level I dial in. There’s minimal color cast, and vignetting is very slight when everything is positioned correctly.Overall, this ND filter kit feels well-built and genuinely boosts creative control on the iPhone. It’s portable, easy to use, and capable of producing more cinematic footage and balanced photos — as long as you’re okay removing your case each time. For mobile creators who prioritise image control over convenience, it’s a strong accessory worth considering.
