I like that it's easy to use out of the box! You can configure your environment in seconds without having to write any code or jump through hoops. The tool also provides good documentation so you don't have to rely solely on their customer success engineers when something goes wrong. Some things could be more intuitive at first glance (e.g., how does one view logs). However, once familiarized, everything works well enough. We are using ConfigCat as our primary method of managing features across multiple teams.
