Hi Ibrahim,
Why do you say they are the only provider to offer clean client? That is
a big claim isn’t it!
StreamVia, which I use, offers a client that is light, clean and
accessible. You can choose to connect to their various servers, which
are located in different geographical locations. They quite good for
streaming media; I always use their VPN to watch BBC iPlayer when
travelling for example. They do offer a special sort of connection to
cope with streaming videos but I have never had to use it. I found their
London based customer service helpful in the one occasion when I needed
help. I pay £3.99 a month and that gives me access to the UK servers. I
believe it is £4.99 a month to have access to all their different
geographical servers. Among other countries, I used their VPN on a work
trip to China and it worked perfectly. And yes, their client works on
Windows and iOS and I am sure it works on Android too.
