The tool is very easy, intuitively understandable for all staff members in our team (including non technical people).
It can handle large amounts data from different sources with ease! I would say that there are some features which could be better improved - like integration into other systems or possibility not only export but also import option within one batch process etc.- We use it as an internal MDQ system so we have full control over everything compared eithr standard ERP tools/SDO's out therse where you need special licenses / support teams available just because they do things differently than us-.
