I've used Jet SmartFilters on a couple of different projects. Its a very powerful filter plugin for Wordpress. I've looked into other plugins, but nothing compares to this one. There is really nothing else like it on the market. Its easy to use, and is very versatile. It has so many advanced filtering options, that many of the other plugins do not have. I know that the Jet plugins for Jupiter X are slowly being removed from templates/pre made websites, but I would love Artbees to develop their own version of this plugin.
