I switched to Comodo after using two well-known commercial heavyweight firewalls, and have never regretted the move. Thanks for a superb product!
The only fly in the ointment is the present stability of Version 3. I’ve just reported a bug about a particular program that crashes due to Defence +, and I notice other reports in the forum about similar occurrences with other programs.
When the rough edges are smoothed out, Comodo 3 will be absolutely unbeatable. I’ve already recommended Comodo to all my friends and fellow computer enthusiasts.
