I had the InvisibleShield on for about a week but just didn't like the texture of the screen. I did improve after a few days, but I definitely missed the smoothness of the a protector like Martin Fields, Boxwave or Clarivue. I ended up purchasing a Vikuiti protector (DQC-160) and am pleased post-install. It's very much like the rigid protectors the manufacturers mentioned earlier offer. It's a tight fit, so it definitely requires clean hands, plenty of scotch tape, and patience, but I'm very happy with the purchase so far.
