Lack sticker

The protection seems to be of good quality, the installation is easy, it is the right size, instructions (for those who can read English) are clear, and the screen is always reactive. Familiar with these products, I am amazed at the lack of sticker which allows after wiping the screen to remove residual dust. Despite my efforts, he stayed two dust on the corner of the screen that resulted in the presence of two slightly visible air bubbles, so obviously a little disappointed.
