The tool seems very intuitive, easy to use even by those who are new in this world! If I had something at least dislike it would have been its price tag (it's quite expensive), but for what you get there isn't any problem if your budget allows buying such software or service.
For me everything was great since we started working with wisdom - from their support team which responded quickly when needed through chat feature where they helped us solve our problems during live meetings etc., also all training sessions were amazing so far. We really value them because after 4 months now almost each member knows how things work here inside out!
