Nibs And Scripts review for King Product Options, Variants

I've never reviewed an app before, but after the great (and patient) customer service, it only seems fair. Prompt response and demo videos to explain troubleshooting or just help with navigating the app. For simple customization options and conditional choices based on product variants is a game changer. Want to add pop-up/description boxes, radio buttons and text fields to customize your products? look no further. Saved a bunch of coding headache and works well with 2.0 themes. Thank you
