NOPE. Do not do it. Awful. I spent an hour setting everything up and then had to create an order to test it (because there's no way to test it without creating an actual order). It let me select an item I had marked as "final sale" even though I'd listed that category as 'forbidden' in the return app. So it shoudn't have been allowed to be returned. It also let me select an out-of-stock item to exchange it for which is a huge headache both for the customer and for the store. It was also showing Australian currency and I looked everywhere for how to change that and couldn't find it. It's also really buggy-- in the return section, it was showing me duplicates of the item I was trying to get in the exchange which would've been so confusing for customers. And if you've already "returned" and item in your order and go to return something else at a different time, it just shows you the item you originally requested to return. The button to go back was very hard to find and I know it would frustrate my customers. All in all, I love the idea of this app but there is SO much more to work out. And so many confusing parts of the setup (i.e. you're "required" to add a menu item in the return portal even though they give you no idea where that menu item will go, what it's supposed to contain, etc.) I'm deleting the app and going back to my good old google form for returns.
