What do you like best?
I like that I am able to share my calendar with other users. Whether it be family, friends, or coworkers, I can create a calendar with the information they need and we can collaborate to keep up with our schedules. I also like that I can receive and accept an invitation to an "event" on someone else's calendar, and it will automatically add to my own calendar. It is great for use in planning family functions or meetings and conference calls with coworkers.
What do you dislike?
I dislike that when a full calendar is shared with me, it needs to be opened in a separate window and is not automatically an option to be included in my main calendar. I think it would be more user-friendly if it was listed in the main calendar's sidebar, with the other calendars you have created. Then we could choose to toggle the events on and off of our main calendar, rather than opening in a separate window. Overall, however, I think Calendar is a great tool and will continue to use it.
Recommendations to others considering the product
I definitely recommend using Google Calendar. It offers great features such as creating events, sending invites, categorizing and color-coding events, and sharing events and the calendar with others.
What business problems are you solving with the product? What benefits have you realized?
Google Calendar allows me to view what events or meetings my coworkers and family member have on any recorded day, so that I may schedule accordingly. Also, by having the ability to share events, I know who can attend, or if we must reschedule.
