Initial setup can be tricky in some cases. Also, there are some space limits that we would hit every now and then while processing internal tables, so we would have to decrease occurs clauses and re-test. These situations could have been related to how the shop installed Xpediter ... it might not be an issue with the tool itself.

Their technical support could be better. There were times where, when we reported bugs, they would fix one bug but add another one. That's probably because of their support model. A lot of organizations are developing software using Agile rather than the Waterfall method, so things are happening all over the place. You get things quicker, but sometimes one fix will break another one or add other bugs.
