Having paid for VPNs in the past, I can confirm that X VPN is up there with the best of them. It works as it should and once you make sure you're running the latest version (this is imperative otherwise there can be bugs) as is provided in this download, there are no issues. I really recommend this VPN to all Mac users.
X-VPN for Mac allows you to connect freely, privately, and securely to the web on your Mac computer. X-VPN works by replacing your personal IP address, which allows you to surf the web anonymously. It's simple to use and loads very quickly.
After downloading the application, simply get connected and open your preferred web browser. No registration is required.
N.B. If you're running iOS10.15 or higher, you will need to authorise extra security permissions. Follow this link for exact info on how to do this.
X-VPN offers several subscription options. You can pay $5.99 per month if you sign up for a year (for a total of $71.88), or a single month for $11.99.
If you run into an issue, support for the software is available 24 hours, 6 days of the week.
