Extremely slow, and it doesnt really give you a USA ip and websites identify as UK and gives wrong currency, other than that if they can make it super fast and actually give proper ip for the country you want it would be up there
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.
