People seem to like it
I manage three freelance clients on separate Outlook accounts plus my personal Google Calendar. I was manually checking four calendars before accepting any meeting. Set this up on a Sunday evening, haven't thought about it since.

Setup took 90 seconds. Not exaggerating.
Blocker mode is exactly what I needed. My team sees when I'm unavailable without seeing that I'm at the dentist or doing school pickup. Just shows Busy.

double-bookings in three months
Previously lost ~1 client/month to scheduling conflicts.
Switched from
another sync tool that kept dropping events. This has been rock solid for four months. Mirror mode is great when you actually need event details on both sides.

Connected Google and Outlook in under two minutes. The longest part was the OAuth consent screen.
