I used to be subscribed to this service. It’s not bad, specially for the price. One of the benefits is that you can manually type a password or phone number and search for leaks (other services won’t let you manually search for such details) but compared to McAfee they include information about far less leaks. McAfee so far detects the most and alerts the quickest (contrary to their so-so antivirus).
McAfee’s leak detection is even better than Norton LifeLock. So far it has alerted me to over 100 leaks (many are combo lists with my details) and LifeLock has alerted me to 3-4.
