The tempered glass by Powertech is a hardened glass, specially designed to cover and protect your mobile phone screen from scratches and other damages. It does not affect the screen's functionality. In the event of a phone drop, it does not guarantee that the screen will not break along with it, but it does provide additional protection. It has adhesive across its entire surface, unlike edge glue glasses that have adhesive only around their perimeter. This helps in better fitting and seamless touch screen functionality. It also prevents dust from getting underneath, which can happen with edge glue when the perimeter adhesive wears out. It is 5D, which means it has undergone special processing to acquire curved edges that cover the entire surface of the phone screen. This way, it is not noticeable that the screen has protection, but the curved edges are also protected. It is compatible with the iPhone 14 Pro Max.
