Easy to use and very effective

Very easy to use and worked very well with no issues. Video tutorial is great. I created a custom taxonomy with the CPT UI plugin then I used this Bulk Term Generator plugin to add almost 100 items to my taxonomy in very quick time. Create the parent items first then the child items. It auto-creates the slug as well (unless you want to customise it).
Also useful for my Woocommerce product categories as well. Thanks Nate.
