Easy to setup and use. The main reason I bought it was because it works with Advanced Custom Fields, You can easily make a product adding form for your products with ACF and create a filters for your fields with this addon.
This plugin absolutely blows my mind. I spent almost $200 for a product filter and a product search plugin from WooCommerce themselves and asked for a refund because neither of them even come CLOSE to the features and functionality of this plugin. Phenomenal! The documentation could use some beefing up but support responded very rapidly and gave me exactly what I needed to know. I love this plugin.
