Anyone use 'Customer Ratings and Reviews Pro + Google Rich Snippets Module' ?

[FoodAssets]

We are interested in the the following module and would like some feedback on it:

http://addons.prestashop.com/en/6144-customer-ratings-and-reviews-pro-google-rich-snippets.html

What we'd like to know is:

1) does it work?
2) Have you experienced any improvements after using it? Please be specific, was your improvements ranking, traffic, or?

We have tried a lot of Prestashop modules and found a lot of them to be buggy and unsupported. Before we jump into another one, we'd like to see some honest reviews from end users.

Using Prestashop ver. 1.6.1.2

Thank you for your time ~
