Rated 3 out of 5 stars

Works great with my calendar with few events in it right now.
But....

If I load a calendar that has a lot to synchronize. The status bar quickly synchronizes saying "synchronizing nnn out of 1000", When it gets near 900, it just starts over (maybe because it is doing another 1000). Eventually sometimes everything freezes up and later a panel comes up asking me if I want to continue a script that is taking a long time. No matter the answer, the interface becomes frozen.

This review is for a previous version of the add-on (1.0.4).
