<b>Otterbox Defender MagGLASS UHD Screen Guard / Samsung Galaxy S10 </b><br><br> Meet the UHD MagGLASS High-Performance Screen Guard. An A-spec tempered glass that is designed and engineered like your digital life <br> depends on it. We test and qualify our glass based on these 6 essential performance benchmarks: <br><br> <b>1) A+ Impact Rating:</b> This is measured by the abilty for the glass (once installed) to retain structural integrity after a direct impact of 6FT. <br> Any glass chipping or hairlines fractures reduce the impact rating (and if larger than 0.02 in diameter disqualify it). <br><br> <b>2) Screen Sensitivity:</b> IE Responsiveness. This is gauged in a side by side comparison of the touch input response time when used with/without <br> the glass installed. This metric is crucial to avoid the input delay (and frustration!) associated with lag-inducing screen guards.<br><br> <b>3) Coverage:</b> Should be easy, right? We thought so. Though it might surprise you, nearly all well known screen protector brands we tried had <br> at least one display area that was left partially exposed once installed. <br><br> <b>4) Screen Clarity:</b> This is where the MagGLASS really shines. The Ultra High Definition glass carries a total thickness of only 0.3mm, it's low profile <br> design aided by the embedded Pixel Grid Technology create an enjoyable, crystal clear user experience. <br><br> <b>5) Scratch Resistance:</b> Our glass features a tough-as-nails true 9H hardness rating with dual tempered layering and reinforced shatterproof <br> construction - all to provide you with complete peace of mind regardless of the elements.<br><br> <b>6) Ease of use:</b> Obvious yet important. Even the best glass in the world is useless without proper installation. Every MagGLASS set includes: <br> screen guard, micro fiber cloth, dust remover, alcohol pad, ensuring a perfect, bubble-free installation every time.
