Tempered glass protectors and PET film screen protectors are both designed to protect the screen of your device from scratches and damage. However, there are some differences between the two that may make one a better choice for your needs.
Tempered glass protectors are made of a thicker, more durable material than PET film screen protectors. They are usually made of multiple layers of glass, which makes them more resistant to scratches and cracks. Tempered glass protectors also tend to feel more like the original screen of your device, as they have a smoother surface and can be more transparent than PET film protectors.
PET film screen protectors, on the other hand, are made of a thinner, more flexible material. They are usually cheaper than tempered glass protectors and are easier to install. PET film protectors are also less likely to shatter upon impact, which can make them a good choice for devices that are prone to drops or impacts.
Ultimately, the protector you choose will depend on your personal preferences and needs. If you want a protector that offers maximum protection and feels like the original screen, a tempered glass protector may be the best choice. If you want a protector that is more affordable , a PET film protector may be a better fit.
