The extension is really good for comparisons, specially because of the "hidden button" that help users hide items and parameters that they don't want.
Maria and the support team are really helpfull! They are great!
I'm looking foward for the next update when the hidden buttons will be displayed in the chart articles as well.
I'm a joomla newbie and I was able to do the basic configuration no problem. Everything that I wanted to do beyond the basic the Cerontek team helped me really fast. I'm really happy with this extension.
