I was drawn to it, because I occasionally like to shoot wildlife videos with my iPhone 15 Pro Max, and thought that the filter would be most helpful during very sunny days.

The kit is comprehensive - you are getting the magnetic filter attachment, the filter, a cleaning cloth and an exceptionally good-quality case to store everything inside. This itself is compact, so would easily fit inside a small bag.

I have mixed feelings about some of the components - the main filter attachment is robust, but doesn't fit well over a case. The one I use is not the thickest, but it was enough to impede the attachment from lining up properly with my phone's lenses. I also don't like the screw clamp - the idea of putting pressure on my phone's screen makes me uncomfortable, especially because you can tighten the screw quite a bit. The magnet works fairly well to hold the filter, though it didn't seem like it had the strongest of holds, so I am unsure for how long the filter could reasonably be held in place, particularly if you are moving around a lot in the field.

Despite the above, the filter itself does make a difference in harsh light, though I would recommend checking some settings first - I didn't realise that my flash was set to 'auto', so it fired underneath the filter, and washed my first attempt at a picture out (the flash is obscured underneath the filter, so the light is bounced back).

Overall, it is a nice kit, but could be improved.
