[reprod]

I installed an Invisishield on 2 Instincts and I can tell you it is not as hard as everyone is making it seem at all.

Clean the screen with some alcohol and let dry...
I recommend doing the steamy shower trick to minimize dust...
Peel off Invisishield...
Spray the solution on your hand (no finger prints) and on the shield
Apply the screen protector and move it around until it is positioned perfectly...
Squeeze out all the unnecessary water (from the center outwards) with the provided sqeegy thing...
Let it dry for about 7 hours overnight and you are good to go the next day!!!

It was sticky at first but after using your fingers for a while and getting some of that lovely human oil on there the screen is essentially perfect. It was much easier typing with the on-screen keyboard but usign the stylus did feel different(more sticky to slide).

The Invisishield does what it was meant to do very well... PROTECT!!!

No experience whatsoever taking one off but I am 99.999856% sure it will NOT ruin your phone!!!
