I am using this VPN provider for a couple of months. The service is working as advertised, unblocks Facebook, YouTube, HULU etc.
They have good speed, surfing web sites is working just fine, video streaming is OK most of the times. The only problem I had is with YouTube HD, the video does not always stream well if in High Definition format, and you sometime have to wait for the buffer to build up, kind of annoying.
The best thing is that there is no traffic limit. I am online pretty much the whole time, and I need a provider that doesn`t slice bandwidth :).
Overall I am happy with them, definitely would recommend to anybody living in China.
