We all know this comes with all apple computers. It works pretty well with my Google Calendar and synchronizes with my phone almost instantly. The calendar is visually appealing and very easy to use. I use this for home, family, kids, and business.
It doesn't always work with Google Calendars but that's a rare occasion. The product itself is perfect for my needs.
This product is so easy to use! If you ever have problems, apple support has helped me with all kinds of problems and they make everything so simple.
I have a very busy life and this product along with my iPhone keeps me very very organized.
