Have you read all the precedents reviews ? If you take all the positive things that they say, and put it all together, you can understand how this component (with the included modules) and the technical support are fabulous. Each precedent review describe exactly the high quality of this software and the support, and the beautiful clima that is present in the forum, where users help each other, and where Alejandro spread is knowledge in help of the users :).
For first we have used the trial version, and I suggest to every one to do the same, in this way you can evaluate if the component satisfy your necessity. Personally we are using this component for building a site about comics, and this is possible because JReview is very flexible and highly customizable. I like very much 3 modules: DashBoard (we have used it as an article thumbnails module and as a Last Entry module), Advanced Search (We are using it for making an advanced filtre) and Fields Module (we are using it in many ways on the site).
English is not my first language, I'm Italian, so I stop here with my review, hoping that I haven' t made so much errors :P.

I want only add that I'm very satisfied of the purchase.

Hi to All :)
