I have been using ZA7 for almost a week. So far, i don't have any bad experience with it. In fact, i'm quite satisfied. The firewall's auto-learn feature is what i like most as selecting Auto-learn instead of Maximum will result in fewer "Allow" or "Block" questions. However, the auto-learn feature will eventually be changed to Maximum after a period of time(about 1 week for me). This is because ZA has done analysing what programs you are frequently using.
