In a single time, I laid a protective film on the screen of my Wiko Cink Five. Respecting the mode of use, I have not had a single air bubble! I noticed compared to other films that it sincrustait perfectly into the screen and does not spill over the edges. The installation of the protective shell silicone does not stumble on film. After 10 days the installation of the film, I note that nothing has changed and that the key on the screen is as sensitive as before. I recommend this product in low price.
