I am also using VPN from very long time. In past I used ExpressVPN service , its paid but really good. I am planning for a holiday in the China and I am looking for best vpn for China, so that I can access my social accounts and suddenly I found  this website and I gained very useful information from here and  when I searched on the Internet I also found Opera Free VPN service, no need to buy a new VPN , just download it in your web browser and use anywhere you want.
