We've just developed a new toy review site with this plugin. We were very impressed with the large amount of options available which enabled us to configure the plugin to work exactly as we needed. This is much, much more than just a simple star rating for comments. And it is quite unfair that other users have rated this plugin poorly just because they could not get it to work easily.
On the website we just built, we have used the plugin to allow both the user and the site owners to review each game/toy. On top of this there are 4 categories per review (each with their own weighting). You can see this in more detail on the finished toy review site here - http://www.toylike.co.uk/reviews/ - just click through to each toy review to see how the rating system works.
