I like that it helps me see what's working for my product in terms of pricing strategy or advertising campaigns so i can adjust as needed. Sometimes its difficult to understand how certain variables affect other ones if they are not shown together at once which makes trying out different combinations more complicated than necessary. Also sometimes there are too many choices available when you don't want all of them included - this could be due to some sort of error but we have had trouble figuring that one out yet! It has helped us tremendously by giving insight into our customer data from several sources (Facebook ads, Google Analytics). We've been able to track changes over time through various A/B tests using their tools such as Optimizer.
