I like that CUX is able create automated tests for my website without me doing it myself - this means i can spend more time with other things which are important as well! It's not clear enough what you should do next in certain situations (e g clicking buttons).
Also there could be some improvements about how often new features get added/improved since we use them every day here at work :) Would recommend if your looking out automation of UI testing or just want an easy way t make sure everything looks good before going live etc.
