After you have cleaned the screen with the included cleaning cloth, freed one one side of the screen protector and places it on the display. Then you should, for example, or the like with a credit card press the film firmly so that all bubbles disappear. With a little pressure that succeeds without problems. DC My first attempt was a great success!
After the first part is done you pull gently the second protective film from the front and as a result you have a wonderful anti-reflective and sufficiently protected display.
The touch sensitivity when operating the smartphone remains unchanged.
This is my first screen protector and therefore I can not compare, but I can hardly imagine that it may go easier.
The price and quality is optimal.
