Rubik Variant Images & Swatch

Within the constraints of Shopify's deliberately incomplete, needlessly complicated, and clunky interface, Rubik is streamlined and fairly intuitive. It beautifully performs a function a great many sellers need. Customer service is outstanding -- interactive, genuinely concerned with helping you, following through, and updating users on changes that affect performance. There are cheaper apps with similar function, but my experience with Rubik and trust in its builders and their commitment to the product have won me over without reservation. Highly recommended!
