One of the few VPN services I've tried that really allowed me to make the most out of a 500/500Mbit connection. Considering their security and the support (especially via IRC), the value on the 1-year subscription seems hard to compete against - especially if you use some 20% off code or similar.
VPN works without any problem, so far. You have to have a little technical insight (it is not plug and play. But maybe that has changed). The staff is excellent and fast. IPv6 is supported. My Android mobile phone also.
The own app for Mac leaks, but not so if using Tunnelblick or similar Mac clients. One more server on continental Europe would be nice. The US & UK servers are useless for me and the Spain is due the distance slow.
