I used this app for the past 6 months and really saw my business grow. The app can import listings that I own from a store (shopify) and directly move everything (pics, text, item weight and size, etc) along with price and quatity syncing to any platform (Ebay and Amazon, namely). This is not only amazing, but on top of that you can do rapid bulk editing in one place faster than the platforms themselves, because instead of 5 clicks and waitin for pages to load, you can do everything in one place. I also used the manifest importer to list some food items from an internal database, and the listing template and quality was excelletn. The app is online best used on desktop only at the time of writing, doesn't have a mobile app.
