I love that this was able to sync my calendar with Google calendars without any problems at all! It also syncs everything seamlessly from one platform to another (and vice versa). Sometimes it takes some time to start up but once you do it is great. They have not made many changes in past year which makes me feel like they are still growing as an organization. A little expensive compared to other solutions out there though their support could be better sometimes when issues arise after purchase/upgrade. We needed something simple so we chose celigo over others because its easy setup & integration into our system.
