I’ve used OkayFreedom VPN occasionally as a backup VPN for a few years. It works, and it’s useful to have it, but there are several issues that keep it from being my primary VPN:
– no control over which server to use within a country
– servers are frequently blacklisted by media sites since their IP addresses aren’t changed often enough
– erratic country selection (although the tendency to select “Germany” when another country is selected seems to be better in the lastest version)
– interferes with other OpenVPN installations on the same computer (e.g., uninstalling them to install its own version). It’s basically just a wrapper around OpenVPN, so I wish they would just forget their own GUI and use straight OpenVPN
– always fails to restore original DNS correctly on exit (reported to them long ago, but still not fixed)
