Add-on is used to promote the products by displaying the most recently added reviews at the store. Reviews appear in left / right column. After moving a mouse over a product, a full review will appear. Configuration allows to select 3 to 5 reviews to be displayed in the pox. In case if there are more reviews, the box header and "..." element will link to the site with products recent reviews.
If you have an individual graphic theme, order the service that will install an add-on to your store.
