CustomBigClocks review for OPTIS Product Options, Variant

I tried Infinite Options first on Shopify. I was really annoyed because I couldn't upload images!!!! WHAT???? I switched to OPTIS and, holy cow, it is so much better. The customer service was great too. It was pretty dang intuitive. I learned it really fast after watching a few videos. Once I understood how to add more options, it was easy.
