On my smartphone I have already changed about 5 VPN-applications, for a while I stopped logging into some applications because of this, but I still needed it, it's my job afterall. I installed it on my computer (I have a Mac 20) and oh my god, everything is flying! So later I downloaded it to my phone, I am using it both, I have no complaints and I am happy. I buy VPN https://www.hostzealot.com/vpn here. I hope I will not have to change it too) As for other pluses a large number of servers to connect.
