Grainwell review for Hulk Product Options

I tried out this app and the features were great but it caused two issues on our website. First, right after the app became active, it caused our photos not to be visible once you clicked on a item. Once that was fixed, customers couldn't add any items to their cart. They did look into this right away but it did not fix the issue. Now I have to wait for them to go back to our original code or go to an older version. I am bummed it is not going to work but it is just not worth losing sales.
