- Five simultaneous connections for account.
- Unlimited and free servers switches.
- Uses OPENVPN


But the problem is in the code. The site is neat, you can download AirVPN for Windows XP, 7, 8 and 10. The graphical interface is simple and well done. The problem is that a connection cannot be established. It loops continuously. The EdoBrim team has tested AirVPN on 3 PCs, with Windows 8.1 and Windows 10 operating systems and does not work on any PC. We have disabled firewalls, antiviruses, exceptions, but nothing. This software doesn't work. Luckily we paid little for the trial only.
