I’ve used this type of test, as well as a competitive benchmark user test and both are EXTREMELY helpful. Lots of people assume because a competitor does something then they should too. But there are two problems 1) who knows if your competition knows what they’re doing. Their users could be suffering and 2) even if your competition does know, you probably want to figure out a way to be competitive and straight up copying will only ever get you at parity.
We’ve been using Zoom for a few years too, and if you’re running a moderated test you can actually give mouse control to the tester and have them test while you record. It’s quite easy!
