I am very impressed and satisfied with the service and support offered by Astrill. I was not very knowledgeable about this sort of software and spent some time trying different services. One company only allowed two server location changes in one month without incurring extra charges, effectively hiding this information on its sign-up page (I immediately cancelled and got a refund!). With Astrill I can switch from server to server with ease for the same price. I signed-up for one month to test it out. Astrill came up top of my list for ease of installation and use, reliability, and price. I needed special help from Support for installing Astrill in Tunnelblick on my Apple TV. Robert provided this quickly and patiently over several chats and emails. Thank you Astrill.
