Nothing to say! The stars speak of them even! If you want to protect your screen: Belkin buy !!!! Faultless! of course, you have the technique! My technique: take off the upper part (of course, the smarphone is first placed on a flat surface and handling the protective film is just above it to achieve rapid installation and limit the arrival of dust) about 1 tier that you put on. Calibrate the lower part of the film and glue the top part you have already unfolded! Once done, you just have to take off the rest of the movie! THERE YOU GO !!!
