I had some trouble getting the app set up but Shahar with customer service responded very quickly and helped me out. One thing with this app is that Track Quantity has to be turned on for it to work. I have over 700 products that are printed on demand, so I wasn't able to use this app for all products (primarily want the low stock alert on the product page for marketing purposes). But, it works great for our bestsellers, which is more manageable in keeping track of quantities. I would love to show "low stock" on products regardless of quantity but the app is running smoothly on my site. Thanks!
