Installation was very easy.
The amount of information that this module gives and the quality of the presentation is sincerely impresive.
I was not using really statistics information about my site as I was using plesk-stat, and I had to go to my server control panel, the presentation was a little unpleasant. Now I've got all this information inside Joomla, only one place to login, and hope to be able to concentrate more in site optimisation.
One of those Joomla components that I will keep using for sure.
Recently after updating to Joomla 1.5.10, and because of a mistake I did following Mike's instructions, the plugin was not working properly. I contacted Mike, and he was so helpful! Well, I granted him access to my site, and he located the error (that was my fault), and even corrected it by himself.
So definitely very good extension and developer, and very kind indeed.
