Installing Google Calendar Sync is a snap -- just download and run. The program is simplicity itself to use. You just log in using your Google account details, then select one of the three sync options (two-way, between Google Calendar and Outlook Calendar; one-way, Google Calendar to Outlook Calendar; one-way, Outlook Calendar to Google Calendar) and tell the application how often to sync.Pros: Quick and convenient.Cons: Only lets you sync your primary calendar, not any secondary calendars.Conclusion: A handy free synchronisation tool with minor flaws.
