I've used VPNs in China for over 15 years and tried 5 or 6 different ones, and pandapow is the only one that works and works consistently. It is great for me, but it is so reliable (and based in Hong Kong) I wonder if it could be a honeypot run by the Chinese government. That's fine if you just used it for news and movies, but if you are doing anything politically sensitive you might want to consider something else.
Mostly worked well. The only operational issue was that if the vpn connection failed, which often happened when I was in China, access would fall back silently to non-vpn. Obviously, this could be a big security risk for some people. The only indication that something was wrong, was a small change to the task bar icon, which is not exactly prominent. Peeved that they dropped support for linux, though they would sell me a $99 router to fix the problem. Speed seems OK. I am still a paying customer though, so they can't be too bad.
