No experience with this product specifically, but TONS of experience with porn filters. For me, the don't work. My theory: they tend to externalize the locus of control, meaning they place the burden of self-control outside the self, and, as I understand it, for genuine recovery to take place, we must learn to operate from an internalized locus of control--the burden of self-control must come from within the self. When I rely on porn filters, I also tend to become obsessed with what they are and are not filtering. Somehow, their very existence on my computer/phone incentivizes the act of trying to get around them. And, though I am not tech-savvy in the least, I am like a goddamn savant when it comes to circumventing a porn filter. A better strategy, for me, is to stay off of all screens (e.g., phone, computer, TV) when I'm alone. When I'm around others, the temptation to look at porn, though not removed entirely, is greatly reduced.
