I've been using Clear VPN for almost a year. It's simple, intuitive, and didn't have any issues. Open the app, select what you need, activate. That's it. Have it on my iPhone, Mac, and Windows PC. On Windows, it keeps asking to log in every time - probably the only inconvenience. Everything else is great.
A really great and user-friendly solution, no-brainer in switching between locations. I love that everything is absolutely intuitive and easy to navigate.
