The best thing about this firewall program it's very easy to use, I like how simple everything seems when you're using armor 2 net personal fire wall! Not much of anything i dislike in particular but there are some minor things such as not being able get notifications for updates or patches if they become available which would be nice (but really isn't too big an issue). It does what its supposed do so no complaints here just keep up with any patching issues because otherwise your computer could potentially have problems down the road especially since internet connections can go out at anytime causing these programs failure/down time etc..
