I like that it's very easy to use for both my personal schedule as well as at work.
It also has great integrations with other programs such as Outlook/Outlook 365 which makes managing schedules even easier! The only thing I dislike about this program is how sometimes it doesn't sync up correctly when you have multiple calendars open in different tabs or windows. This happens more frequently than not but still needs some improvement. Use it - it will make life much simpler! Scheduling of appointments and keeping track of them all.
