We just installed the rating-widget for our Global Music Talent Contest. After installing just about every other widget we settled on this one.
The support staff was crazy responsive to us. They not only helped us implement the widget, but they also performed customizations to our widget that met our specifications, and they did it over Christmas!
These guys are great to work with! If you are looking for a rating-widget for your wordpress site this is your answer! The plugin works great and they will customize it to your needs.
I suggest getting their paid version. It's super affordable and it comes with nice analytical and reporting features.
