Yes, That's 3D Printed review for Amazon MCF/ Walmart MCS by M2E

Bad UI, logs don't function properly, syncing 3 products took half a day. Connecting an Amazon marketplace actually connects all the marketplaces in that region. This is not explained anywhere, and created duplicate orders for us, costing hundreds of dollars. They seem like they have at least one other well-liked functional app in the app store, so the state of this one is unacceptable.
