Summit Chemical Shop review for Buy Button channel

Sorely disappointing. I've spent weeks on issues relating to the buy now buttons. It's not very flexible, there is no product image zoom (the product and thumbs are tiny), and the variants only change with the drop down selector not the thumbnail change (which is sloppy UX in my opinion) and the buy now sections on my site load slowly. If I could, I'd look elsewhere. Might have to code the products myself and only use button code.
