The easy to use interface of precursory, as well is being able to customize what you need it for in terms of forecasting your needs are met by this program! I've used other programs that were more complicated than necessary but not with Precursor; they have made things so simple from start-to finish!! Nothing really bad about anything yet because everything has been great thus far.
If there was something i did like or disliked then its hard to think up an answer since all aspects haven't had any problems at all. !
