I bought the Invisible Shield (just to cover the screen) and I'm super happy! Professionally installed, lifetime warranty, in and out service (at my mall).
Professionally installed? Really? Where did you get that done? I tried like hell to apply the Zagg and a BSE skin and I was ready to kill the sadistic designers by the time I was finished. Needless to say, my install attempts did not go smoothly and I'm back to a screen protector and a case. Just can't bring myself to keeping it naked.
