Installation is a breeze after scrupulously cleaned to remove any traces screen from dust, laying the glass protection is performed simply and adheres directly on the smartphone.
The touch feeling is super nice, it slides better than the slab of the screen itself, a treat to use everyday.
For that price, you get 2 protection. See in time but a priori, once we asked for quiet a while.
Plastic protective film, it's really an old story. A purchase recommended.
