With Reviewer you can create and manage reviews on your website. With just a few clicks the plugin is installed and you’ll have all you need to get started on writing reviews
No fuzz
The Reviewer core plugin is not meant to be a one-size-fits-all solution. It is pouring the foundation to build a house or even a skyscraper if you’d like. 
This means that the plugin is designed to have all the core features you need to start writing and managing reviews, and the ability to extend these features to fit your exact needs.
Beautifully designed and coded
I take great pride in writing beautiful code and that can be seen in the Reviewer plugin. I know users (like you) don’t look at the code / don’t care about it, but this is one of the most important things to build a solid, stable and maintainable plugin. Trust me.
Extensible
Every WordPress site works and looks differently. 
looks: By default Reviewer brings you standard looking templates that should fit most themes. Want to up your game? you can override every template and make things look exactly how you want. 
works: Need to modify how something works? The plugin is made to be easily extensible, and we have a ton of documentation that will also show how you can accomplish doing so.
