P blockers are not 100%. Google images goes around it. Sometimes when I travel and the place or country does not allow P, guess what, Google images are allowed. My point is not buy the P Blocker and go to Google images nor is don't buy the porn blocker to not allowing yourself to stop watching porn. You can always go around it. Now if you are into some specific sites then the investment might be worth it. But if P blockers work then my all means use it. This P thing sucks!!!
