The only complaint (1 star deduction) is the lack of any orientation lines on the slide. It's hard just pure eye into one photo, the film perfectly straight. I also know films in which there was such a grid or lines, whereby a better orientation in the alignment was not possible. This is slightly more complicated and costs here unfortunately the one star because it was supposed to be easy to incorporate such alignment aids.
On the whole, the film is, however, easy to apply and to be recommended.
Please note -> The film can, due to the rounded edges of the iPhone, do not go quite to the edge. There are still people who just do not understand or want to understand.
A little tip when attaching -> In the bathroom the shower turn on and wait until steam forms. This binds the dust and you can slide a bit attach safer without feeling to have the every movement of dust kicking up.
