I prefer this over the Shopify solution. I haven't had any issues with it and it reduces the amount of customers who may have missed details when placing an order.

This app is easier to use than others I've tried. Whenever I've had issues customer service knows the exact answer I need and respond within a minute. They seem to be working on new features all the time - regardless this app is MUCH easier than trying to make my own feeds in Google Merchant Center.
