For a long time now I've been extolling the virtues of the military inspired Zagg mobile screen protectors, aka Invisishields. For those of you who may not know, the Army use the same material to protect the blade edges of helicopters in the desert so that the sand doesn't damage the rotors. They are very good. But, they are an absolute pain for the majority of mammals with opposing thumbs and forefingers to fit. Only a few unique individuals can easily fit them. This summer I took my iPhone to Cyprus, and found that in the heat, the adhesive failed more than once and whilst shoving it into a camera bag pocket, it rolled up and ended up a right mess. Having said this, fitted correctly, in the right temperature conditions, they feel quality and offer a rubberised finish to your screen, which doesn't affect the responsiveness of the device at all. They are however, prior to installation, floppy, and this makes the world of difference. The case mate screen protectors on the other hand are fairly rigid, albeit thin transparent plastic 'rigid'. The upshot of this is that they're far, far easier to fit. Case mate advise the user to fit the protector from the bottom to the top of the device. You peel the white tab off, which removes the plastic backing, and then simply stick it on. I found however that there was far less margin for error if you installed it edge to edge. The adhesive removes most air bubbles as it sticks, but removing remaining ones is a doddle. Whats even more impressive, is that, so long as you've successfully cleaned the screen first (with the supplied cloth) and so long as there are no fibres left on the screen (AT ALL) the screen protector will be almost completely invisible.
As a solution, I prefer the case mate.
