We were looking for a filter plug-in that was compatible with our shops with 30-70 thousand products. Until then, no other filter was able to process such quantities satisfactorily and fulfil our wishes. Due to our good experiences with wpintense (Scalability Pro), we took Dave at his word and installed the plugin. Particularly noteworthy are Dave's tireless improvements and first-class support. Almost all wishes are answered immediately and a solution is sought and found. The filter plugin is also therefore able to filter extensive shops extremely quickly and reliably. We are thrilled with the performance of the filter and the wpintense team! Of course we will now buy the "lifetime" licence.

The developer is always in touch in discord. Filter working very fast (i use in ajax). I use woof before, but after 10 attributes itsa working slow. I use with Scalability Pro. Its realy very fast. Thank you Dave.

Best effing Woo filter on the planet. Period. All other filters turn to DB to get terms and stock levels. This is fine with small sites. 18k products. Sort by brand? Dynamically populated filters based on category contents? YITH, Themify etc – you know that it adds around 9 seconds to page load. Hell no. With SSF i can barely notice speed difference but filters work like they suppose to.
