I used Astrill when it was running the beta version and became the first group of paid users.
Now I've been using it for almost a year and use it daily to gain access to Facebook, Twitter, Youtube and other websites and resources even they are blocked by the damn GFW.
The speed was unbelievable fast, I can download files from rapidshare just like I was abroad.
I used to contact Astill twice, the first was a short while after I became a paid user, and got no response, and the second time was when I tried to set VPN on my Blackberry and got response in time. From this point, I can see the improvement of Astrill.
I also become friend of Astrill on Twitter and Facebook in order to get the latest info from them.
I can still remember how excited I was when I use Astrill to gain access to youtube and watch the videos with high speed, at that time Astrill only offers several IPs in the US and later they have UK. And now they have also AU,DE,FR,IR,CA etc. That is really awesome.
Regarding the price, I personally think it reasonable in comparison with StrongVPN. But here I suggest Astrill provide users some more packages, like single IP, Single Country with cheaper prices. Seldom of users use so many IPs in different countries although the price is really competitive.
