I've set up and used Joonbot since April. It's super easy to get started and integrate into your website, when I did need a little help the customer support was incredibly quick to respond and made sure I was happy with everything.
I created a large tree of communication, included free response, videos, pictures, and generally tried to utilize all the features they offer.
I really think JoonBot is an excellent choice for anyone who needs a no-code chatbot that's filled with tons of features.
