Hard to beat I agree. There are two issues with them:
1. Pricing. I was told by one of their developers months ago that they are considering including home plan in standard pricing. Didn't happen. When you add up StealthVPN (for faster speeds via Astrill applet vs OpenVPN) + home plan, it gets expensive. I prefer to keep now 2-3 VPNs for US Netflix instead of one. To be honest I am waiting for Black Friday sale, hoping they will offer a nice deal for 2 years.
2. Some of their IPs are so popular already, they should consider changing them. Example: being connected to NL server, Google is showing me chinese ads everywhere I am. The obvious reason for this is because Astrill was preferred solution in China, so Google also know who are the majority of users coming from Astrill's IPs and therefore show targeted chinese ads. Beside, their IPs have been blacklisted on so many websites already and the Google captcha is annoying too.
