I really like Freedur coz it’s the 1st app I meet that is so simple to use, though I’m an IT expert. All you have to do is just simply launch the application; you don’t need to know about VPN, setting, etc. And the Whitelist function is very useful! I think if it can sync with the web that will be better.
Any way, if any friend of mine asks me for solution of VPN to get through the GFW, I’ll always suggest them use Freedur. It’s cool and simple, worth every penny XD
