The so called Chinese "Great Firewall" really takes effect and I can not open many websites. So, I need some effective tools to climb over the great wall, one of the most wonderful sites in the world. As for climbing over the wall, strong vpn really helps. I had tried some free climbing-wall tools before I met strong vpn. I have to admit that strong vpn is the best. However, other than climbing over wall, I have another goal, speed. It seems this vpn, like others, cannot overcome the speed bottleneck surfing internationally. Overall, I think it helps.
