When I applied the first film exactly as directed on the screen, I noticed that in width were missing 2 mm. I have informed the Company atFoliX by email. The Reaktiion was prompt: I was asked to send us photos to assess the situation better. I came to the request and was informed that a timely manner exactly matching sheets were resupplied. Two days later they were in the post office. Super product, super Kommumnikation, great service: 5 stars!
