The first time of Mumbi disappointed! I've repeatedly placed these films to mobile phones, Navis, cameras etc. So far, everything was always 100% right. The films are the best of what is on the market. Unfortunately, the cut of the film was too large. Since I'm a foreman, I did not give it back to measure after the first failed attempt with a digital caliper after. The upper and lower film is too big in all sections 0.01 to 0.12. Thus, the film can not fit snugly. As should the cutting line may recalibrate. I have 2 set recut because my son his DS3 obviously wanted absolutely. But unfortunately This results in a ridge, and the film takes the edge blow. Looks now hold S ..... From :-(
