This is a very solidly constructed filter kit! There is a clip-on bracket adapter which has a thumb screw to tighten it down until it snugly fits onto the iPhone camera lenses. It is designed for pro iPhones with three camera lenses. It fits perfectly on both my iPhone 14 Pro and 15 Pro Max. It is magnetic so the polarizer lens snaps right onto the bracket and can be removed quickly as to not interrupt shooting different scenes. I like that there is also a cold shoe if you have other accessories to attach. Plus its magnetic bracket can also be used with other 67 MM filters which is really a plus! There is a soft cleaning cloth and zippered soft case included.

The only issue I have with this set-up is the potential to crack the iPhone screen if care isn’t taken to not over-tighten the screw. The other issue I see is how advanced these new iPhones are and how easy it is to correct exposure and highlights in the phone and the necessity for a CPL filter isn’t what it used to be. I took a ton of test images but the only two which showed the difference were the shots taken of bright clouds on a sunny day using the iPhone automatic settings. In that situation, yes, this works well and I would say if you are an outdoor scenic photographer using an iPhone, this would be a nice filter kit to have and a time saver as you could keep shooting without having to manually adjust exposure. I will definitely use it for sunset beach shots when I get the chance. I think for the price it is a good value.
