Data Feed Watch: Product Feeds

We've been using DataFeedWatch for over a year. We have three Shopify stores connected, each with several different product feeds for different platforms. It provides the extra configuration options we need that other feed builder apps were lacking. Some of the features we find really useful are being able to append static values to product urls, using Google Sheets for custom lookup tables (for when we want to supply different product information than what we use in our Shopify store), and dynamically setting values based on product sku/name/etc. Whenever I've had a question, their tech support is very responsive (I usually use live chat, which is very convenient). Overall we would recommend DataFeedWatch to anyone looking for a robust product feed generator.
