From a functionality standpoint, this was the only app that provided the tools we needed and now that we have some work arounds in place, it seems to be working well (we're only 2 days in, so we have limited data but testing and early customer usage seems to indicate all is good). My biggest issue is the lack of documentation. That is somewhat offset by the prompt and responsive support I received from the GCH team, but I really prefer documentation to help better understand the product. I think general ecommerce stores will have no issues but we're a little more complicated and needed to deal with in store pre printed Shopify gift cards and how to navigate them within GCH (you really can't so we kept a our physical cards as a separate product). Even with some quirks, it's well worth it to have a POS compatible product with most of the gift card features that native Shopify is lacking.
