Very good quality!
I have an iPhone 8 and have been trying out the Filmic Pro app. It soon became evident that I needed ND filters if I wanted to film at 24 fps, 1/48 and a low ISO. They came yesterday and I went out this morning to do some video. What a difference when using ND! I had to stack the ND8 and ND16 to tame the Arizona sun, but I got to film with my desired settings. The quality of the filters and clip is excellent and I believe that I received full value for my money. Thanks for filling a real need.
I was very happy with the quality of the iPhone Scape ND and Polarized filters. They fit over my iPhone 7P and my iPad Pro cameras very well, and they have made a great difference in my photo quality.
