I've been using this app for about 5 months now. Initially we had quite a lot of problems with orders under our minimum amount slipping thru. Support really wasn't great and I was told that I could always uninstall the app if I am not happy. It also does not work with other sales channels so be prepared to still get orders below your minimum thru FB and other third parties. Must just add that the last couple of months app has been running smoothly and I am quite happy with results now.
