Two Areas for Improvment Rated 4 out of 5 stars
This is a very good product. I took it through a lot of testing and found only two areas needing improving. Both areas has the potential of creating serious and dangerous situations. First, some web page shows before the filtering is completed. For example, with Java script enabled, the following web page related to religious music shows for about 10 seconds before it detects my keyword filter, "movies": (http://music.yahoo.com/track/609630).
The second area needing improving is the main filter itself. It does not work on some web pages. For example, on the website (http://www.minitex.umn.edu/mnlink/), you to search for any kind of material and the results of the search will be clearly displayed without any filtering regardless of how ProCon Latte 18.104.22.168 is set up. Neither the Main Filter or the Profanity Filter works on this site. Some of the search results on this website have pdf files that can be directly downloaded on your computer.
Overall its a good product and I plan to give a financial donation after these two areas are corrected.
