The most useful feature to me was how easy it made scheduling meetings with coworkers who live all around America! It also helped us keep track if everyone attended or not which I really liked because sometimes we would have people miss our scheduled time slot so this way you can check what happened during your absence as well without having anyone tell their side story about why they missed out appointment for example like some other services do where someone has an excuse but then when asked said "I don't know". Sometimes there are issues such as slow internet connection etc., however these problems were resolved quickly by support team via email/phone calls within hours after reporting them while using web browser (not mobile app). This service makes life easier especially working remotely since my work days started later than others due weather conditions therefore making communication difficult between myself & co-workers living miles away apart hence requiring face2face interaction instead being able communicate through chat only.
