I use their premium VPN service, it's a good service to bypass geolocation barricades (I.e. "this video is not available in your country") and is also useful to dodge NATs. You get your own public IP address (of a /24 block per server) which even enables hosting on 3G connections and other force-NATed connection types.
Average server speed is at 3 Megabit/s, that's acceptable for sites with broadband requirements.
It features a very high coverage in countries and switching the server and/or IP address is FREE (Server switching is not included in many other paid VPN services other than HMA Pro VPN and costs extra on alternative competition).
Nothing phishy about HMA website at all, and their vpn service is top notch. No popups either or anything to be concerned about there. They serve customers all around the globe and have servers is more than 20 countries. They have been in VPN service for a long time, but are best known for their anonymous proxy and free proxy lists. Tons of customer reviews on their site and at http://VPNandUsenetReviews.com
Fast, only ads at top of page, and reasonably secure. Of course they want you to buy their virtual private network service (want to someday, when I have money) which guarantees more security... but for casual internet browsing this is fine.
