You may not have a basic understanding of this VPN, do not know how good this APP. We only need to subscribe to this app on a device. We can use vpn at the same time on mac, ipad, ipod, iphone and other devices. This is very convenient for us to go out and work. I believe that not a few VPNs can do this, so spending a little bit of money on this is quite cost-effective for us. I will use vpn at the same time on mac, iphone, and the speed will not be affected at all. For a long time, there has never been any problem that has affected my use, and this VPN can rival other VPNs between various functional modules. With such a good VPN, why didn't I choose it?
