Has anyone tried the VDC-7 for control/video/telemetry?

Just wondering if anyone has experience with the VDC-7 or VDC-12 from Foxtech?

Looks like a viable solution for combining control, video and telemetry. It looks similar to Herelink but the user can use their own RC controller, GCS and monitor.

Thanks in advance for any feedback.
