Power Support Anti-Glare Film Set for iPhone (Original)
I have run through a number of screen protectors over the years.  This one worked fine, the anti-glare is legit, and the texture on the surface gives some nice traction, although it takes a few minutes to get used to instead of the normal slippery feel of the phone screen. What was nice was that the thing went on easier than any other protection device I have used, no problems with dust or bubbles, easy as pie.
