If you have an issue about uninstalling blocking/filtering softwares then there is nothing to uninstall with this filter. All you have to do to ensure it is permanently on is to block the website in your block list so that you can only access the block/filter settings on other devices than the one you have the DNSfilter on. Very easy to setup and benefit from.

Easy of use. It was easy to get a bunch of our clients into the system, and once we figured out the script to deploy it - they all started populating pretty fast. The interface is also much cleaner than some of your competitors.

Deployment/implementation is very easy and the admin console user interface is very intuitive. Support has been very help for any questions/issues I've had.
