It's fast to use for my needs as I'm looking at news articles from around Canada about different topics of interest that are related in some way or another with what we do here (medical cannabis).
The interface can be difficult if you're not used to it but once one gets past this initial learning curve they will get all their information needed without too much trouble! Nothing so far - everything is good!! Great service overall though there could definitely still room for improvement especially when compared side by side against other services out there like Google Alerts etc., But nothing really comes up right now which isn't great either :-/.
