InvisiGlass Screen Protection is the best screen protector available, engineered for strength and clarity and tested to meet optometric standards. The result is a crystal clear screen protector that keeps your screen safe from damage while still giving you an incredible screen experience. InvisiGlass screen protectors are 100% real, flexible glass, engineered to a hardness rated at 9H, which is one mark below diamond. This exceptionally tough material is damage-resistant, which helps to prevent scratching. Inflexible materials can be brittle, causing them to snap under pressure. InvisiGlass is engineered with FluidFlex technology which gives it a unique elasticity. This enables it to withstand and absorb the shock of impact without breaking, much like a tree or a tall building. A precisely applied screen protector provides greater protection for your smartphone. InvisiGlass Screen Protection can be professionally applied to your smartphone in store by a trained professional, using a specially-developed application system. If you can't make it to your local outlet, we've included Easy Align stickers/ an Easy Align frame to add precision to any application. The frame helps/stickers help to align the screen protector so precisely, it's hard to know it's even there. The flexible glass has been carefully manufactured to add strength while preserving the smooth feel of regular glass. It is also amazingly thin which preserves the sensitivity of the touchscreen. This ensures a glide and touchscreen-sensitivity that is almost identical to the naked screen. Belkin screen protectors preserve the vibrant colour, resonance and clarity of your screen so you can enjoy the brilliance of each and every pixel. To ensure our screen protectors are of market-leading clarity, we use the same testing methods as those used for eyeglasses by optometrists. Every TrueClear InvisiGlass iPhone Screen Protector is backed by a Limited Lifetime Warranty. So if your screen protector is ever scratched or damaged, send it back and we'll be happy to replace it.
