If you want a fast, free, easy-to-use VPN, just get AnchorFree's HotSpot Shield. Most downloaded free VPN in the world. AnchorFree's CEO was also selected as one of Inc's 30 Under 30 this year.

DISCLAIMER: AnchorFree's CEO is one of my dearest of friends for nearly 12 years, but that's not why I'm promoting HotSpot Shield here. It just really is that good, and I use it all the time on public hotspots.
