I reckon its shit. Just spent 10 minutes trying to install it because a stupid training session I'm booked for uses it (I've already got Zoom and GoTo Meeting, don't really want another one, especially anything by Microsoft) and of course it insists I have a Microsoft account, which I don't, then asks me what I want to use it for, then tries to direct me to skype instead, then asks me to download the desktop app (I've already downloaded it you cretins, we're in the middle of installing it right now!) and then I try to start it, and a blank white box appears. I've now got a purple circle of "maybe I'm thinking of doing something, maybe I'm not" running, but that's all. Nothing actually happening.
Maybe it'll actually do something before my training session next Wednesday, but I'm not banking on it. Its not as it my PC is that tardy, its a decent i7, with 32GB of RAM, SSDs, and kept devoid of excess crap (apart from MS Teams, of course).
I was sufficiently grumpy about the training as it was. Its for a charity I'm a trustee of, I have to pay £18 for it, then it turns out its only 1.5 hrs, and its scheduled from 1100 to 1230. Could they possibly have found a less convenient timeslot if they'd really, really tried? It will effectively prevent me doing my usual work at that charity that day, as its 7.5 miles from home, and I'm not driving back and forth twice, and still missing half the working day.
