The best thing about this bot is its capability of connecting with other chat applications like WhatsApp, Skype etc which makes it more useful than others out there in market for sure! I have no dislike or dislikes at all as far i am concerned but if you are looking forward to develop an interactive conversation between your customers then definitely go ahead!! This tool has been very helpful while developing my own business application where we can easily communicate our clients using messenger apps without having them sign up themselves. As mentioned above, easy communication via messengers helps us save time so much by not needing any manual work from client's side either they want their queries resolved immediately or need some information shared over email/call center system. Also when compared to call centers (which needs lots of human resources), messaging app saves lot of money too because less manpower required here only few people will be working behind these chats instead many calls would require multiple agents who could help resolve.
