I liked that they can create bots without coding skills or having programming experience! They're very fast when replying so its easy for me as an admin of my site to reply back quickly if needed - super helpful :) The only thing i found was their prices were expensive compared other services but overall good price-wise because all features are included at no extra cost which is great!! You will need some basic knowledge about what makes up each answer (if there's one) otherwise sometimes people may not know how certain things work within our website haha.
We use this mainly just through internal communications; however we have had positive experiences using them recently by getting questions from users who don't understand why something isn’t working well enough etc..
