I easily installed this on my iPhone XS, following the directions provided and using the wipes and adhesive strips. I learned years ago to do it on a clean hard surface like a desk, and to blow away all dust from the area before starting. Even the tiniest speck of dirt will mess it up, so cleanliness is key. Other than that little caution it's as easy as can be. My previous one cracked after a hard fall but the screen itself was undamaged.
