Pen Savings review for Smart Product Filter & Search

Simple and really flexible app -- got great custom implementation support from Clara. We launched a new Shopify site using a custom 3rd party theme for Shopify. We've used the app for a good while and found it easy to expand out filter options over time. We have a very large amount of SKUs, so we need a lot granular filters that can nest easily within different categories by both tags and collection. There was a visual bug with the app's product/collection card layout overriding out new one and the team quickly made some tweaks for free. Clara was the team member who helped; super quick response time (less than 10 min back and forth email chat). Recommend for stores with similar filter needs.
