Variator: See Product Variants

The app does what it promises. Don't hesitate to reach support because compatibility with Themes seems to require a little intervention from the dev team, they did it in no time.

The App messes up the usability of Shopify 2.0 filters, and when support was contacted they broke our Theme functions, not a good support experience, unfortunately...

The app works perfectly. There was a small problem with my theme, but the support was able to solve the problem within a short time.
Support response time was extremely fast.

Now everything works fine and I can see all my variants.

App did not remove the "Options" button as I thought it would, and simply put an "Add to Cart" button below it. It did show the variants separately. I decided that the app wasn't for me, and deleted it. In my theme (Dawn), deleting it did nothing -- the collection pages still showed it. Had to get the developer to remove it. Note that they work 8-5 weekdays only, on Pakistan time. Because I put the request in on Friday afternoon in the US, it wasn't until Monday morning that it got removed.

After setting it up, right away, a liquid error is shown on all my collection pages.

Does not delete its code after deleting the plugin, the liquid error is still on my collection pages.
