It's never worked well for me, e.g., when responding to third party calendar invitations, when moving meetings with others, when using two-factor authentication, when adding contacts on multiple devices.
Both of those add-ons have always been clunky and brittle for me. They have caused me to miss appointments and have also occasionally messed up my contact data.

I would never, ever use these add-ons for work.
