Lockhart's Authentic review for OPTIS Product Options, Variant

We needed a quick solution to add a required checkbox to a subset of our products that ship separately from all others. This became necessary because some customers were not seeing or perhaps reading a note to that effect. The required checkbox confirms their understanding before one of those products can be added to the cart. The reason we are leaving this very positive rating is that the app's support rep (Julie) responded immediately to assist us in implementing what was needed, including custom CSS code, and did so professionally.
