Excellent application with a couple hiccups – Astrill VPN Client Review

In terms of stability, speed, etc, this is the best I've found by a fair margin. But switching from one device to another when I can only have it on one or so at a time can be a pain if you have "Reconnect" or "Always On" on, which can make your devices fight you for access and can lead to locking up. It's minor and by being careful to log out it's easily remedied.
