I like how easy it was, no hassle of any kind! The customer service has been wonderful as well so far but there are definitely some bugs here or something because sometimes we can't get our money out after scanning an item (we scanned items at different times throughout my day).
But other than this nothing really bad about using mishipay!! It's great if you're looking into getting your business online by having customers be able do transactions without them needing cashiers/clerk assistance which helps cut down costs quite significantly when running small businesses such us ours.
