For today's review we will be looking at an iPhone 5/5S screen shield from Tech 21. The Impactology Impact Shield is designed to keep your iPhone 5/5S safe on the one area that most cases do not protect – the screen. Unlike other shields this is a multilayer structure that is designed to absorb and dissipate force away from the point of impact. It is composed of three layers – a hard top layer designed to spread the impact force, a middle layer using BASF BulletsShield Protection polymer to absorb the impact and finally a soft base layer that further absorbs impact force.
