The app has been very helpful for our team with all of its features including video conferencing tools as well! Nothing really so far that I dislike but maybe sometimes it can be too slow when you are trying do something like open an email or chat window? Try this out if your looking into communication at work!! We have used many different apps over time from Slack through HipChat (which we still use) etc., however nothing quite came close until now because they were just not built right nor did their support seem able/willing enought o help us get what needed done accomplished within deadlines. They seemed more willing than others who had similar offerings which was nice considering how important getting things completed ASAP could potentially mean regarding business success later down road. !
