The ease of use, how much customization is possible with this bot's API! When I first started using it for my own business (I am an eCommerce store owner), there were some limitations that made me think twice about continuing to invest in these services - but they have since been resolved or addressed by their support team who are very helpful as well!! There really isn't anything bad at all here- so far everything has worked perfectly. And if you're looking into other bots such like Slackbotz etc., then definitely give them more than just one try before making your decision because once again we've found success through our usage experience thus far :) We primarily used Rapportive within chatbots/chat apps which allowed us great insight from potential buyers while also being able provide quick answers when asked questions via text messaging during checkout process / sales flow.- This was mainly due towards people not having access yet to computers & phones therefore unable navigate website properly without.
