Easy to block sites with one click of the button. Didn't take long to figure out how to edit or remove blocked sites. I would like to see better instructions. I don't understand what regex means so I don't use it. I like that I can use wildcards so it will block a domain. Works very well for my needs.
I changed my rating to four stars because "Hand Of C'thulhu" tells me to Google the answer instead of saying thanks for your input. Signs of an arse.
