This mod does exactly what it says, in that it requires your customers to purchase a product before they can review it - This helps stop people leaving reviews which are fraudulent/spam. When submitting a review, your customer will receive a warning due to the order status being invalid/non existant. You have complete control over which of your order statuses are valid for a customer to review with. For details, see the screenshots in the Additional Images tab below
You can see a demo of the reviews being declined at http://demo.jaygilford.com/
Simply choose a product and try and review it
You can purchase the product, and then review again, which should allow you to review this time (be sure to be logged in)
