Is anyone successfully using qground and crossfire?

I’m starting a new build. I want to be able to run most of my commands from qgroundcontrol and monitor most/all of my way point missions. I have a full crossfire module which I understand can be powered out of the tx and connect to qgroundcontrol over Bluetooth.

However I’m finding mixed information on telemetry over crossfire. Is anyone doing this successfully with crossfire telemetry? Or is the telemetry speed too slow to use effectively?
