JerryRigEverything's torture tests of the iPhone 17 Pro demonstrate the durability of Ceramic Shield 2. The screen proved highly resistant to scratching, with only minor marks appearing at level 7 on the Mohs hardness scale. This is a significant improvement compared to typical glass, which scratches at levels 5 or 6. JerryRigEverything praised Ceramic Shield 2 as the best they have encountered. Apple's own promotional video also showcased the material's resilience against a mineral tip. The residue left in Apple's video was from the tip itself and wiped away easily. The author shared their personal experience with an almost year-old iPhone 17 Pro. This device shows no visible scratches on its front glass, not even micro abrasions. The author attributes this excellent condition largely to Apple's Ceramic Shield 2. This technology is designed to offer superior scratch resistance, supporting the claims of its effectiveness.
