I like how easy it is for my team members (and myself) to access our calendars via this app. Some of us have over 30 calendar appointments per day which makes keeping track difficult! Also very time consuming when trying to make an appointment or find someone in another office who's available at certain times. Try out Nucleus as they are currently working hard to improve their product however there really isn't anything bad about using them right now. Keeping all communications within one central location has been helpful to me so far with having more than 40 individuals within 1 business unit.
