I have not had good results and stopped trying. I have had some usable results, but on careful inspection there were subtle problems or needless convolutions that implied a different solution was being used than was actually the case. The sort of thing that works but is prone to misinterpretation by the next one working in the code.

Based on this I'm very against using it for things the user doesn't have significant knowledge of. Some coworkers seem to be having better success but I definitely get the sense they are reading and editing the results carefully. I don't find it that much if any of a productivity gain so I stopped trying for now.
