THese guys have created a super platform taht can measure customer satisfaction on your store, by asking the customer to give a review to common questions about the store, the procedure etc.
you get then to see those reviews and drill down to problematic sections, according to customer reviews
The Addon is for all v4.x and you can download it for free on our store
new version compatible with all v4x CS-Cart stores
