I was going to give the plugin 4 stars because there were some quirks that needed to be worked out but I later (4 months to be exact!) discovered they were due to a theme specific issue. I also didn't get any response in the support thread regarding the issue I had so I was a little disappointed from that as well, however, WP Customer Reviews is no doubt the best plugin I've tested so far for user reviews. I even managed to find a solution in the support thread to enable responsive design functionality with v2.4.8 so that has been cool since I use a responsive theme. I'm honestly very excited for the new version which is slated to be released albeit some delays.
