I've been gathering information and looking for a screen protector. Then I saw this screen protector on YouTube: ZAGG invisibleSHIELD EXTREME commerical (with an iPhone 4) It is the "Extreme" version of the invisibleSHIELD. The same product is also available for Samsung Galaxy S3 at the manufacturer's website. Here, a YouTube video of some kids at Best Buy (employees) testing the invisibleSHIELD EXTREME on someone's Samsung Galaxy S3. They hit the screen with hammers, (i.e., a normal-sized hammer and then a... mallet,) cut it with a box cutter, and then drop it face-down onto the floor. Here is a video of another torture test of the invisibleSHIELD Extreme by a YouTube user. I am very impressed. I'd like to know: how does the screen protector feel to the touch? Does it decrease the touch sensitivity of a phone? Does it reduce clarity? Does anyone have any experience with that "Extreme" product?
