There's nothing I dislike about this product yet! It has been great for us so far; we have had no issues whatsoever with it (and if there were any concerns they would be addressed immediately). We've realized better communications between our team members - which improves efficiency as well- by getting instant feedback from each other through chat messages in real time without having face2face conversations or emailing back & forth everytime an issue arises within one department/team member / client etc..
