What is the difference between Pro; Pro Plus and Premium??
pro allows access to software and driver updaters and other locked features.
Plus and Premium are Pro with additional installs (3 and 5 Devices (Android, Windows, Macintosh) respectively). Plus and Premium come with Speccy and Recuva Pro (though they’re pretty close to the same as the free of these) and (I believe) Premium comes with the VPN Kamo.
