I like that you can set up rules to block different types of websites (for example porn) without having multiple subscriptions if your ISP doesn't allow this option through their own interface - which is often what happens! There was also an issue with one rule not working properly at first but after contacting support they got back in touch within minutes offering me another solution free until we figured things would be fixed correctly again next time around so no issues there now either. Not much really as everything seems fine from my perspective though some people may find certain features more useful than others depending upon use case/needs etc.- mainly just have fun trying them all out yourself when signingup :) We've been able prevent our kids using any questionable apps & accessing anything dodgy via mobile devices whilst away too!!
