Smart Product Filter & Search

This app has helped solve a number of issues we had on our Shopify store. We are able to have a customisable filter tree, hide out of stock products, as well as group colour swatches for better user experience and much more. When I encountered a small error/glitch within the app I contacted support where Helen promptly responded within the day and resolved my issue immediately. So far very impressed by this app and their customer service offering.
