They’re adding new servers around the world every few weeks, as well as adding to their 140+ servers in San Francisco.
Right now they’re offering three months for $21 if you want to try them out. They also have a 7-day money-back guarantee.
They seem to do an especially good job getting around the firewalls in China, and they can also protect your iPhone or Android phone or tablet.
