We have been using cipa filter for over 5 years now, it has never let us down! It's so easy to use that even my mother can do it herself (she loves doing housework!). There are also many add-ons available from reputable companies like Kaspersky which we've used with no problems at all in our previous products too!! I would definitely recommend this product as there really isn't anything negative about its performance or ease of usage - just great customer support if you ever need any help :) The only thing i dislike sometimes when having issues with certain websites/apps being blocked by filters but not sure why it happens because their staffs will always be more than happy to assist me whenever needed though they're usually pretty quick :). Security online especially banking sites etc., keeping ppl safe while browsing through social media platforms such as Instagram & Facebook.
