Its UI is easy to use for desktop and iPad/iPhone. Downloading it in my Firestick was also easy and very helpful for my purposes. I have not had the chance to talk to their Customer Support team, mainly, because I have not needed it. I use it every single day in all my devices. I am a Freelance Copywriter, therefore, I go out to work at cafés and Atlas VPN really keeps my information safe. I have not tried all their features.
This is a personal nitpick but their iPhone widget could be "prettier" or more "aesthetic."
I wanted to feel safe when working at a local café, accessing a supermarket's WiFi, or an airport's WiFi, and Atlas VPN has accomplished that for me.
