Variant Image Wizard + Swatch

Excellent product and stupendous customer service. I transferred to this from a different app, and am amazed at how superior it is.
This variant manager does what others can't: it let's you set swatches at the product level, instead of having to create a library of dozens of differently-named color swatches used globally. Great for optimizing the product page and showing clearly what is in and out of stock. Multiple options, great flexibility. I am very impressed by this company and by Jake, who is tireless.
I give it my highest recommendation.
