It is super cool for showing the test sessions live to team members - so they can watch the tests and see where the users are and aren't looking on the website or app. You can settle a lot of arguments when you can really know if the participant didn't actually see something or not, or if they were
looking at something for a long time, or all around the screen - they were
clearly confused or couldn't find what they were looking for. It makes it so much easier to figure out where the problems are.
It's super useful to get more detail on how people are using your website, it shows you what they're looking at as it's happening and you can really see areas they struggle with and what features work well. It's super easy to use and worth the investment !
