Excellent application. It's use has resulted in increased sales for products that are often overlooked. Works well! Would like to see an option for a bit more control over frequency of display relative to other items in the rotation.

This app is exactly what I need and then some. I'm writing a second review because of the outstanding customer service provided. There were a couple of minor issues that needed to be addressed and they were --- within minutes!

This is a very effective tool for adding options and variants that don't require pricing. It addresses a severe limitation in Shopify's product structure.
