This one is by far the best comments and opinions component, in terms of implementation. Flexible and adaptive, it can insert an interactive space good in design, and intuitive features.
You can customize it exactly to your needs, to fit in the graphics and options provided.
There is no useless function, everything is planned and thought to be effective, even email notifications.
I would also like to thank the support team, which performs a great job ; in both pre-sales and after sales. This is the second RSJoomla! extension I've been using, and I must admit that I have rarely seen such a good quality service. Congrats !
