Three reasons: First reason: there is in the light in my office a very disturbing rainbow effect. This is here that few meet but is nevertheless disturbing to me. Second reason: when I was a scratch on the adhesive side of the film, which looked then like a Staubfussel and had similar effects. In general there was especially on edge ever interfering bubbles. Third reason and in the end the main reason why I'm back discarded. She was not very scratch resistant. Within a few days I had it several scratches. My current film looks after umpteen weeks still almost intact, even though the mobile phone is regularly transported along with keychain.
