well i had the invisible shield but couldnt get on with it. didnt like the texture (is like orange peel) and felt quite rubbery so i took it off.

a word of warning with this tho, when i took mine off it was so well fixed it gave me a big fight. bowed the touch screen surface outwards as it was peeling off and as a result i now have a small bright spot near the top of my display and the touchscreen sometimes makes a faint clicking/crunching noise. it does still work perfectly so at least theres that i guess..

by the way i tried puncturing the back part of the protecter since i didnt want to use it and well, that material is stupidly strong!!
