I'm using Zagg invisible shield. They have kiosks in SM megamall, SM North, SM MoA and Robinsons galleria. They probably have in other malls, too. It's a bit pricey at Php 800.00 as screen protectors go, but I like its rubbery feel. If you have clammy hands, you should probably skip this.
Also, when I bought mine, they had to order it from their supplier and I gave 50% down. It took 3 weeks for it to arrive. If it doesn't arrive it 3 weeks, you have the option to refund your down payment. I got mine at galleria and the guy manning the booth did a good job installing the protector. A lot of people don't like the orange peel effect of invisible shield. I, however, don't mind since it's only really noticeable when looking at it at an angle.
