Which VPN do you use?

What VPN are you using on Android, and would you recommend it?

I've been using ZoogVPN for the last few months, and it's worked out better than I expected. At first I only installed it because I needed a VPN while traveling, but I ended up keeping it. The app is easy to use, and I don't have to mess with settings every time I open it. I mostly use it when I'm connected to hotel or café Wi-Fi, and everything has been stable so far. Browsing feels smooth, videos load normally, and I haven't run into random disconnects. For my everyday needs, zoogvpn has been reliable enough that I don't even think about switching anymore.
