I just installed the InvisibleShield too. It is slightly rubbery, but doesn't diminish the use of the screen too much, imo. The comment about it being like an 'orange peel' is drastically overexagerated, although the texture appears similar when viewed from an angle. I bought the full body. The phone is now less likely to slip through my fingers onto the floor. I am overall happy with the purchase.

When you install it, remember to use enough water. That is how you get the air bubbles out. Mine is air bubble free.

If you do decide to remove it, remember to peel it at 180 degrees, not 90. That way you aren't yanking the screen outward.
