I like how easy it was to set up, no technical knowledge required! It has been very helpful in keeping us safe online when we are not around our computers or phones with internet access.
We have found that some of my colleagues do feel self conscious about using their mobile devices as much since they can be tracked easily if someone wants to view your browsing history/data etc., so this helps them keep track more securely while still being able use other apps for work purposes at times without worrying too greatly because you cannot browse away forever (in most cases).
