I installed the plugin after finding problems with my theme and a straightforward way to implement structured snippets manually. It is really easy to configure and use and it works first time. I did have a small conflict with my theme, and inquired about the problem. I received a response and a css snippet within an hour. I am really impressed that people give their time and effort to help others even when the plugin is free. It's people like this I trust and will buy paid versions from - they have proven themselves.
