The most positive thing about this app would be that it provides you excellent quality of sound so while having face time conversations, there won't even feel like someone else was sharing their space or room. I dislike how sometimes when using multiple people can chat in at once - but if one person has stopped talking then other may continue speaking without knowing they are interrupting them because your screen will still show activity from previous participant's chats! Great for small business purposes where everyone needs easy access into meeting rooms / offices & also good as virtual training tool as well since all participants get full HD experience through webcam/mic input (as long we have internet connection). It helps save tons off our office budgets too now by giving us extra benefits not only limited within physical locations!!
