I got a filter 3 weeks ago and it is amazing!! How could I have lived without it?!!
Just by installing it, it helped me not even try to look at anything bad. For 3 weeks I was able to stay away from evil without a problem.
At first my Yetzer Hara told me not to get a filter because it would block my work, or websites that I like...blah blah... But it's fully customizable and I have had no problems.
And one day when I was bored and alone, and for the first time I tried to look at evil.... But the filter held up and did its job very well! I did not see anything bad.
This filter thing is amazing and I don't think a Jewish home should go without one.
