A week ago I received the Invisible Shield from Zagg in the mail and was very excited. I read the instructions, saw some installation videos on youtube and after 1 hour of preparation i was ready for the install. The installation process is a nightmare as you have to apply the solution while keeping the shield from sticking to itself and its a PIA to align correctly. I installed the back cover first and after many tries I had it correctly aligned but it didn't fit perfectly meaning there were areas that the shield did not cover completeley such as corners which are the most prone to damage. Next I installed the screen protector OMFG what a POS. It had bubbles all over even after using the squegee card. I thought I'd give it a few days for them to clear up as Zagg claims that within 24 hrs they disappear. They did not go away and it made the screen look bad especially on a white background. Needless to say the smaller pieces are also a nightmare to install. Anyways, today I saw my phone and got tired of looking at that Zagg crap and at the sticky feel it gives the phone and took it off and went back to what I had before. I had the siliicone case from the sprint store and the screen protector from the sprint store which had worked perfectly since november: not a single scratch and no dust problems. So really beware of the Zagg products, at least I got it for free so it didn't hurt to throw it away.
