I haven't contacted Microsoft technical support because of this tool, but for some other things I have, and I found them quite lacking. We had trouble with Azure Firewall, where we wanted logs from our VMs, but reaching out to Microsoft took a prolonged time to the extent that we were wondering why Microsoft was unable to get its own logs to us, which occurred a few months back. I would rate Microsoft support around 6.5 to seven, as they don't directly interact with medium-sized MSMEs, always referring to their partners, so it differs based on the partner's level of relationship with Microsoft.
