Hey ,
To be honest and I don't want to trash on MI , but I feel like the improvements / addition of new features are pretty limited.
Web App Health -> If you are using a proxy , this is probably pointless. Only supports 443 and 80/http on other ports
WAN Health -> To be this is the best feature of MI. Speeds tests are a nice addition , but can't test the upload.
VOIP Health -> pretty much useless since this is sending ICMP probes instead of UDP/RTP. So this isn't really testing 'VOIP'.
I personnaly wouldn't recommend it , unless you need a feature.
