MicroPuzzles review for ZenBox: Bundle Builder

DO NOT DOWNLOAD - THIS APP IS NOT SUPPORTED. From Shopify: "BoxBuilder: DIY Product Bundle is currently unsupported...it may not work as expected until the developer updates it. You can contact the developer for support or uninstall the app and find an alternative in the Shopify App Store." We've had this installed since October and it has gone down multiple times for large swaths of time. Their latest patch fails to load or fix the issues. Customer's are building boxes and then left hanging (it never actually gets to the checkout point), Super disappointed in the product and the "customer service". We're actively looking for a new app as there are/were too many problems over an extended period of time. Save yourself the aggravation and avoid BoxBuilder: DIY Product Bundle by Staytuned.
