We engineered this guard like your digital life depends on it - we therefore test and qualify our glass based on these 6 essential performance benchmarks: 1) Impact Rating: This is measured by the ability for the glass (once installed) to retain structural integrity after a direct impact of 6FT. Any glass chipping or hairlines fractures reduce the impact rating. 2) Screen Sensitivity: This is measured in a side by side comparison of the touch input response time when used with/without the glass installed. This metric is crucial to avoid the input delay (and frustration!) associated with lag-inducing screen guards. 3) Coverage: Should be easy, right? We thought so. it might surprise you, many well known screen protector brands we tried had at least one display area that was left partially exposed once installed. 4) Screen Clarity: The High Definition glass carries a total thickness of 0.3mm, it's low profile design aided by embedded Pixel Grid Technology create a crystal clear user experience.

Even the best glass in the world is useless without proper installation.
