If you don’t want to display all the product reviews at the same time, you can set a maximum number through the “Number of reviews to display” option. Value “zero” matches with no limit.
In this case, to allow users to view more reviews you must activate the “load more” feature in settings dashboard field.
According to the settings, “load more” can be a link or a button.
You can also change the text of the “load more” button or textual link.
