enable reviews

I am using stamped.io for product reviews. This plugin is set up but I need to add the widget or code to the product and categories pages.

sample code would be <?php echo do_shortcode('[Woo_stamped_io type="widget"]'); ?>

This needs to be done site wide.

I have reviews set up in the theme as per:
