The best thing about this tool was it's ability to do things I could not have done myself - easily! It does all sorts of data analysis which makes sense when you're trying to figure out what your customers want or need from YOU (not vice versa). There are some features we didn't understand well enough at first but now they make perfect sense once used them more than once so there aren't many complaints here. If anything, maybe try using premoney before jumping in? We were able to get great insights into our customer base with just one month worth of usage.
