Its ok
Its ok for viewing your Google calendars and adding events. What doesnt work is you cant change the calendar an event is in. I find I have to frequently open Apple iCal app to move events to their correct calendar.
Or I could delete the event and recreate it but when you enter a lot of information in the event its a hassle to readd all that.
