I checked out this plugin because I was looking for a good way to gather customer testimonials, and have them display with proper schema markup, getting a passing the rich snippets.
After testing over a dozen different testimonial plugins, I found that this has integrated and modified the code from another plugin - http://wordpress.org/plugins/wp-customer-reviews/.
As far as the rest of the functionality goes, I wasn't after those features, but it seems pretty slick and does work well. My only complaint is that there is no list of shortcodes that I can find anywhere.
