The Spigen tempered glass is a hardened glass, specially designed to cover and protect your phone's screen from scratches and other damages. It does not affect the screen's functionality. In case of a phone drop, it does not guarantee that the screen won't break along with it, but it does provide additional protection. Its special treatment makes the phone screen visible only from the front, blocking vision from any angle. This protection is useful if you frequently use public transportation and do not want those around you to look at your screen. Conversely, it is not suitable for gaming or watching videos, as it darkens the screen. It is compatible with the iPhone 14 Pro.
