The UI is very intuitive to use as it's designed by engineers who have vast experience in building systems of this nature.
It also works well if you are familiar enough w/ docker or k8s environments which makes getting started easier than some other tools I've used before (e.g., etcd). There isn't anything really specific i dislike about armo but there could definitely be more documentation available online. If your looking into an integrated toolset then look at what others recommend; we found ourself having too many different applications managing various aspects such as authentication / authorization across multiple microservices & containers running within my organization - Armo provided us all those benefits under one roof!
