So I took these photos with my iPhone 13 Pro Max. The first photo is with no filter and then progresses from ND2 to ND32. I did not further alter these photos in anyway, it is just what my camera automatically adjusts to. I do think the colors and details are a bit more vibrant in the photos with the filters.

What I also love about this set of filters is that the design works with a case. I have a case on my phone and I did not have to take my case off to use this. The magnetic design is also great if you want to be able to take off or put on the filter really fast. I've seen some designs where you have a separate filter for each ND, this is just all in one.

Very good filter system with the most common filters you need. I use this on an iPhone 15 Pro Max using a filter holder for taking pictures and filming. Thanks to the excellent magnetic adhesion, the filters sit firmly on the holder, but are still easy to change in seconds. The image quality is not negatively affected by the filters and is fantastic overall. The price-performance ratio, especially in the set, is great.

Great quality and fits my iPhone 14 pro.

I ordered this polarizing filter for my iPhone 14 Pro Max and I'm happy with it. The clamp fits well, even with a thick case. The cutout prevents light from coming in from behind - a clever solution. The polarizing filter works as expected, especially with glass fronts. The magnetic system is convenient, but makes rotating it a bit tricky. The results are impressive, as can be seen in the attached video. However, the effect is different for different reflections. As a complement to an ND filter, it is very useful. Overall, a solid product for smartphone photography enthusiasts that noticeably improves image quality. There are small weaknesses, but the advantages clearly outweigh them.

I am very impressed with the quality of the materials this device is made of, it is metal, of good quality, it feels and works like something really durable. I mean, it is not an electronic device, but once you have it in your hand, you know you made a good purchase. I used it this weekend with my iPhone 13 Pro to record some videos and the filter helped me a lot to almost completely eliminate the glare from the sun and the reflections from the windows of the vehicles and the surface of the sea.
With the included filter, the sky takes on a more intense blue tone that greatly increases the contrast of the photos and videos. If you have used a polarized filter, you know what I am talking about.
I have only tried it on the iPhone 13 pro, and it fits this model of phone perfectly. It is appreciated that it comes with a hard case and a cloth to clean the filter and the adapter as such.
Very good and recommended.

Great Product for iPhone 13 pro max
