Pros: Easy to install for the Joomla beginner. The fact that you only need you Clicky's Site ID, and nothing else makes it a breeze to set up. Great support, I immediately found the answer to my question I was having issue with it getting to track at first, but it turns our I just needed to put the module in a position that exists within my template.
Cons: No real control. Anyone more than a beginner in Joomla will find this module unnecessary. The parameters didn't seem to want to make any changes that I set. What I now have is the tracking code Clicky gave me in a custom HTML module. It works just as good and you'll have complete control over it.
Overall, this is a great module for beginner webmasters, anyone else can can safely pass on this.
