Color swatches and theme

Hello there,

I’m interested in your color swatch extension (https://www.woothemes.com/products/variation-swatches-and-photos/) but I’m worried it will conflict with my theme. Is there a way to test it before purchasing, or could someone run a diagnostic of some sort? $99 isn’t cheap, and I already purchased a plugin that did not work with my theme. Trying to avoid the same mistake twice.
