PC ‑ Custom Product Options

Great app and fantastic customer service. I have (almost literally :P ) a tonne of customization options and Shopify's variations couldn't handle the pressure (and was far too complicated for even the products with 20-30 options). Product Customizer is very simple to use and handles my 'tonne' of options with ease :).
When recently switching my theme, something went awry and my customizations disappeared. Kim from ShopStorm got back to me very quickly, was very helpful and fixed everything for me :).
