The best thing about this tool is its ability to give you an accurate picture of your product's performance compared with competitors' products, which helps improve marketing decisions for future campaigns or promotions! I don't like anything specific yet - it seems pretty good so far though; however there are some minor issues here &there (ease/speed) but nothing too serious at all :) Overall great experience using epicconjoint thusfar!! We've been able use our data from previous studies as well compare new customers vs past clients we had previously used other tools such as Google Analytics etc., This has helped us make better business decision regarding client retention rates over time periods between surveys.
