Cool rating tool, but…

It is a very nice and interesting tool, but the basic (free) version it is so poor in options, almost none! And this fact it’s accentuated by the dozens of features and options available only for the Pro version.
I would love to have a trial for a short period of time, to test and decide after. Otherwise, seems to be a great tool for visitors as well as for the rich snippets that can be shown in search engines and by that having a greater click-through rate and more visitors – no doubt, a cool plugin!
