About the product, it exudes quality: screen that does not scratch, no fingerprints, no way alters the touch and brightness. The glass is very well packaged, delivered with a cloth with alcohol, another for wiping tape to remove dust films, a manual is even provided. No bubbles under the screen, a single touch in the middle and it fits perfectly. I advise you to apply it in a bathroom where there is generally less dust.
In summary, a great product for a great brand.
