I like that it allows me to target market segments with specific demographics, which gives us an edge over our competition in terms of reaching certain customers when they are more likely to be interested in what we have to offer them. It's not really something that would drive most people mad, but some users may find the product interface too simplistic or difficult to navigate at times - mainly due to lack of training from their side! We're using this tool as part of my team's strategy to get better insights into who needs help selling products online (we do eCommerce). This helps us understand customer behaviours so we can make relevant offers across different channels.
