We have been using it for over two years now, our team of around 30 people works mostly remotely from different places in Europe (including countries where English isn't spoken). It allows us communicate directly with each other without any additional costs - very convenient! As soon as we get new information about something relevant or important, all members receive notification through email / Slack messages instantly. No need to waste time waiting until someone gets back online after working hours etc., which would otherwise take up precious minutes/hours per day. There are some minor issues that can be improved like adding more options to set notifications preferences but I think they're actively looking into this problem since last year. Our whole team has benefited enormously by being able to work together without having to travel every week. The benefits include saving money on transportation expenses alone plus productivity gains across multiple departments due to better collaboration between colleagues both physical & virtual.
